CHAPTER 6 LAN Screens This chapter describes how to configure LAN settings. This chapter is only applicable when the ZyWALL is in router mode. 6.1 LAN, WAN and the ZyWALL A network is a shared communication system to which many computers are attached. The Local Area Network (LAN) includes the computers and networking devices in your home or office that you connect to the ZyWALL’s LAN ports.
Chapter 6 LAN Screens Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established.
Chapter 6 LAN Screens 6.3 DHCP The ZyWALL can use DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) to automatically assign IP addresses subnet masks, gateways, and some network information like the IP addresses of DNS servers to the computers on your LAN. You can alternatively have the ZyWALL relay DHCP information from another DHCP server. If you disable the ZyWALL’s DHCP service, you must have another DHCP server on your LAN, or else the computers must be manually configured. 6.3.
Chapter 6 LAN Screens 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group. The ZyWALL supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2).

CHAPTER 7 Bridge Screens This chapter describes how to configure bridge settings. This chapter is only applicable when the ZyWALL is in bridge mode. 7.1 Bridge Loop The ZyWALL can act as a bridge between a switch and a wired LAN or between two routers. Be careful to avoid bridge loops when you enable bridging in the ZyWALL. Bridge loops cause broadcast traffic to circle the network endlessly, resulting in possible throughput degradation and disruption of communications.
Chapter 7 Bridge Screens 7.2 Spanning Tree Protocol (STP) STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a bridge to interact with other STP-compliant bridges in your network to ensure that only one route exists between any two stations on the network. 7.2.1 Rapid STP The ZyWALL uses IEEE 802.
Chapter 7 Bridge Screens Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello BPDU after a predefined interval (Max Age), the bridge assumes that the link to the root bridge is down. This bridge then initiates negotiations with other bridges to reconfigure the network to re-establish a valid network topology. 7.2.

CHAPTER 10 Wireless LAN This chapter discusses how to configure wireless LAN on the ZyWALL. 10.1 Wireless LAN Introduction A wireless LAN can be as simple as two computers with wireless LAN adapters communicating in a peer-to-peer network or as complex as a number of computers with wireless LAN adapters communicating through access points which bridge network traffic to the wired LAN. To add a wireless network to the ZyWALL, you can connect an Access Point to a port in the WLAN role. 10.

CHAPTER 11 Firewall This chapter shows you how to configure your ZyWALL’s firewall. 11.1 Firewall Overview The networking term firewall is a system or group of systems that enforces an access-control policy between two networks. It is generally a mechanism used to protect a trusted network from an untrusted network. The ZyWALL physically separates the LAN, DMZ, WLAN and the WAN and acts as a secure gateway for all data passing between the networks.
Chapter 11 Firewall Your customized rules take precedence and override the ZyWALL’s default settings. The ZyWALL checks the source IP address, destination IP address and IP protocol type of network traffic against the firewall rules (in the order you list them). When the traffic matches a rule, the ZyWALL takes the action specified in the rule. 11.
Chapter 11 Firewall Packets have a source and a destination. The packet direction matrix in the lower part of the screen sets what the ZyWALL does with packets traveling in a specific direction that do not match any of the firewall rules.
Chapter 11 Firewall By default, the ZyWALL allows packets traveling in the following directions.: • LAN to LAN These rules specify which computers on the LAN can manage the ZyWALL (remote management) and communicate between networks or subnets connected to the LAN interface (IP alias). " You can also configure the remote management settings to allow only a specific computer to manage the ZyWALL.
Chapter 11 Firewall • WAN to WAN By default the ZyWALL stops computers connected to the WAN from managing the ZyWALL or using the ZyWALL as a gateway to communicate with other computers on the WAN. You could configure one of these rules to allow a WAN computer to manage the ZyWALL. " You also need to configure the remote management settings to allow a WAN computer to manage the ZyWALL. See Chapter 4 on page 89 for information about packets traveling to or from the VPN tunnels. 11.3.
Chapter 11 Firewall In order to do this, you would configure the SECURITY > FIREWALL > Default Rule screen as follows. Figure 127 Block DMZ to VPN Traffic by Default Example 11.3.2 From VPN Packet Direction You can also apply firewall rules to traffic that comes in through the ZyWALL’s VPN tunnels. The ZyWALL decrypts the VPN traffic and then applies the firewall rules. From VPN means traffic that came into the ZyWALL through a VPN tunnel and is going to the selected “to” interface.
Chapter 11 Firewall Figure 128 From VPN to LAN Example In order to do this, you would configure the SECURITY > FIREWALL > Default Rule screen as follows.
Chapter 11 Firewall 11.3.3 From VPN To VPN Packet Direction From VPN To VPN firewall rules apply to traffic that comes in through one of the ZyWALL’s VPN tunnels and terminates at the ZyWALL (like for remote management) or goes out through another of the ZyWALL’s VPN tunnels (this is called hub-and-spoke VPN, see Section 14.17 on page 292 for details). The ZyWALL decrypts the traffic and applies the firewall rules before re-encrypting it or allowing the traffic to terminate at the ZyWALL.
Chapter 11 Firewall Figure 131 Block VPN to VPN Traffic by Default Example 11.4 Security Considerations " Incorrectly configuring the firewall may block valid access or introduce security risks to the ZyWALL and your protected network. Use caution when creating or deleting firewall rules and test your rules after you configure them.
Chapter 11 Firewall Once these questions have been answered, adding rules is simply a matter of entering the information into the correct fields in the web configurator screens. 11.5 Firewall Rules Example Suppose that your company decides to block all of the LAN users from using IRC (Internet Relay Chat) through the Internet. To do this, you would configure a LAN to WAN firewall rule that blocks IRC traffic from any source IP address from going to any destination address.
Chapter 11 Firewall Now you configure a LAN to WAN firewall rule that allows IRC traffic from the IP address of the CEO’s computer (192.168.1.7 for example) to go to any destination address. You do not need to specify a schedule since you want the firewall rule to always be in effect. The following figure shows the results of your two custom rules. Figure 133 Limited LAN to WAN IRC Traffic Example Your firewall would have the following configuration.
Chapter 11 Firewall Allowing asymmetrical routes may let traffic from the WAN go directly to the LAN without passing through the ZyWALL. A better solution is to use IP alias to put the ZyWALL and the backup gateway on separate subnets. 11.6.1 Asymmetrical Routes and IP Alias You can use IP alias instead of allowing asymmetrical routes. IP Alias allow you to partition your network into logical sections over the same interface.

CHAPTER 14 IPSec VPN This chapter explains how to set up and maintain IPSec VPNs in the ZyWALL. First, it provides an overview of IPSec VPNs. Then, it introduces each screen for IPSec VPN in the ZyWALL. 14.1 IPSec VPN Overview A virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption, authentication, access control and auditing.
Chapter 14 IPSec VPN A VPN tunnel is usually established in two phases. Each phase establishes a security association (SA), a contract indicating what security parameters the ZyWALL and the remote IPSec router will use. The first phase establishes an Internet Key Exchange (IKE) SA between the ZyWALL and remote IPSec router.
Chapter 14 IPSec VPN You can usually provide a static IP address or a domain name for the ZyWALL. Sometimes, your ZyWALL might also offer another alternative, such as using the IP address of a port or interface. You can usually provide a static IP address or a domain name for the remote IPSec router as well. Sometimes, you might not know the IP address of the remote IPSec router (for example, telecommuters).
Chapter 14 IPSec VPN Figure 172 SECURITY > VPN > VPN Rules (IKE) The following table describes the labels in this screen. Table 64 SECURITY > VPN > VPN Rules (IKE) LABEL DESCRIPTION VPN Rules These VPN rules define the settings for creating VPN tunnels for secure connection to other computers or networks. Click this icon to add a VPN gateway policy (or IPSec rule). Gateway Policies The first row of each VPN rule represents the gateway policy.
Chapter 14 IPSec VPN Table 64 SECURITY > VPN > VPN Rules (IKE) (continued) LABEL DESCRIPTION Click this icon to display a screen in which you can change the settings of a gateway or network policy. Click this icon to delete a gateway or network policy. When you delete a gateway, the ZyWALL automatically moves the associated network policy(ies) to the recycle bin. When you delete a network policy, it is just deleted. Click this icon to establish a VPN connection to a remote network.
Chapter 14 IPSec VPN " Both routers must use the same encryption algorithm, authentication algorithm, and DH key group. See the field descriptions for information about specific encryption algorithms, authentication algorithms, and DH key groups. See Section 14.3.1.1 on page 258 for more information about DH key groups. 14.3.1.
Chapter 14 IPSec VPN " The ZyWALL and the remote IPSec router must use the same pre-shared key. Router identity consists of ID type and ID content. The ID type can be IP address, domain name, or e-mail address, and the ID content is a specific IP address, domain name, or e-mail address. The ID content is only used for identification; the IP address, domain name, or e-mail address that you enter does not have to actually exist.
Chapter 14 IPSec VPN • Instead of using the pre-shared key, the ZyWALL and remote IPSec router check each other’s certificates. • The local ID type and ID content come from the certificate. On the ZyWALL, you simply select which certificate to use. • If you set the peer ID type to Any, the ZyWALL authenticates the remote IPSec router using the trusted certificates and trusted CAs you have set up.
Chapter 14 IPSec VPN Step 2: The remote IPSec router selects an acceptable proposal and sends it back to the ZyWALL. It also finishes the Diffie-Hellman key exchange, authenticates the ZyWALL, and sends its (unencrypted) identity to the ZyWALL for authentication. Step 3: The ZyWALL authenticates the remote IPSec router and confirms that the IKE SA is established.
Chapter 14 IPSec VPN 14.4.1 SA Life Time SAs have a lifetime that specifies how long the SA lasts until it times out. When an SA times out, the ZyWALL automatically renegotiates the SA in the following situations: • There is traffic when the SA life time expires • The IPSec SA is configured on the ZyWALL as nailed up (see below) Otherwise, the ZyWALL must re-negotiate the SA the next time someone wants to send traffic.
Chapter 14 IPSec VPN Figure 177 IPSec High Availability When setting up an IPSec high availability VPN tunnel, the remote IPSec router: • Must have multiple WAN connections • Only needs one corresponding IPSec rule • Should only have IPSec high availability settings in its corresponding IPSec rule if your ZyWALL has multiple WAN connections • Should ideally identify itself by a domain name or dynamic domain name (it must otherwise have My Address set to 0.0.0.

Chapter 14 IPSec VPN In most cases you should use virtual address mapping (see Section 14.6.2 on page 271) to avoid overlapping local and remote network IP addresses. See Section 14.14 on page 286 for how the ZyWALL handles overlapping local and remote network IP addresses. 14.6.2 Virtual Address Mapping Virtual address mapping (NAT over IPSec) changes the source IP addresses of packets from your local devices to virtual IP addresses before sending them through the VPN tunnel. 14.6.2.
Chapter 14 IPSec VPN 14.6.3 Active Protocol The active protocol controls the format of each packet. It also specifies how much of each packet is protected by the encryption and authentication algorithms. IPSec VPN includes two active protocols, AH (Authentication Header, RFC 2402) and ESP (Encapsulating Security Payload, RFC 2406). " The ZyWALL and remote IPSec router must use the same active protocol. Usually, you should select ESP. AH does not support encryption, and ESP is more suitable with NAT.
Chapter 14 IPSec VPN In transport mode, the encapsulation depends on the active protocol. With AH, the ZyWALL includes part of the original IP header when it encapsulates the packet. With ESP, however, the ZyWALL does not include the IP header when it encapsulates the packet, so it is not possible to verify the integrity of the source IP address. 14.6.5 IPSec SA Proposal and Perfect Forward Secrecy An IPSec SA proposal is similar to an IKE SA proposal (see Section 14.3.

A VPN (Virtual Private Network) tunnel gives you a secure connection to another computer or network. Each VPN tunnel uses a single gateway policy and one or more network policies. • The gateway policy contains the IKE SA settings. It identifies the IPSec routers at either end of a VPN tunnel. • The network policy contains the IPSec SA settings.
Chapter 14 IPSec VPN 14.10 IPSec SA Using Manual Keys You might set up an IPSec SA using manual keys when you want to establish a VPN tunnel quickly, for example, for troubleshooting. You should only do this as a temporary solution, however, because it is not as secure as a regular IPSec SA. In IPSec SAs using manual keys, the ZyWALL and remote IPSec router do not establish an IKE SA. They only establish an IPSec SA.

Chapter 14 IPSec VPN Figure 192 VPN for Remote Management Example 14.17 Hub-and-spoke VPN Hub-and-spoke VPN connects VPN tunnels to form one secure network. Figure 193 on page 292 shows some example network topologies. In the first (fully-meshed) approach, there is a VPN connection between every pair of routers. In the second (hub-andspoke) approach, there is a VPN connection between each spoke router (B, C, D, and E) and the hub router (A).
Chapter 14 IPSec VPN 14.17.1 Hub-and-spoke VPN Example The following figure shows a basic hub-and-spoke VPN. Branch office A uses one VPN rule to access both the headquarters (HQ) network and branch office B’s network. Branch office B uses one VPN rule to access both the headquarters and branch office A’s networks. Figure 194 Hub-and-spoke VPN Example 14.17.2 Hub-and-spoke Example VPN Rule Addresses The VPN rules for this hub-and-spoke example would use the following address settings.
Chapter 14 IPSec VPN 14.17.3 Hub-and-spoke VPN Requirements and Suggestions Consider the following when implementing a hub-and-spoke VPN. The local IP addresses configured in the VPN rules cannot overlap The hub router must have at least one separate VPN rule for each spoke. In the local IP address, specify the IP addresses of the hub-and-spoke networks with which the spoke is to be able to have a VPN tunnel. This may require you to use more than one VPN rule.
CHAPTER 15 Certificates This chapter gives background information about public-key certificates and explains how to use them. 15.1 Certificates Overview The ZyWALL can use certificates (also called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key. Certificates provide a way to exchange public keys for use in authentication.
Chapter 15 Certificates Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The ZyWALL can check a peer’s certificate against a directory server’s list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure). 15.1.
Chapter 15 Certificates Figure 196 Certificate Details 4 Use a secure method to verify that the certificate owner has the same information in the Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your situation. Possible examples would be over the telephone or through an HTTPS connection. 15.4 Configuration Summary This section summarizes how to manage certificates on the ZyWALL.

CHAPTER 17 Network Address Translation (NAT) This chapter discusses how to configure NAT on the ZyWALL. 17.1 NAT Overview NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. 17.1.1 NAT Definitions Inside/outside denotes where a host is located relative to the ZyWALL.
Chapter 17 Network Address Translation (NAT) " NAT never changes the IP address (either local or global) of an outside host. 17.1.2 What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side.
Chapter 17 Network Address Translation (NAT) Figure 215 How NAT Works 17.1.4 NAT Application The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using IP alias) behind the ZyWALL can communicate with three distinct WAN networks. More examples follow at the end of this chapter.
Chapter 17 Network Address Translation (NAT) 17.1.5 Port Restricted Cone NAT ZyWALL ZyNOS version 4.00 and later uses port restricted cone NAT. Port restricted cone NAT maps all outgoing packets from an internal IP address and port to a single IP address and port on the external network. In the following example, the ZyWALL maps the source address of all packets sent from internal IP address 1 and port A to IP address 2 and port B on the external network.
Chapter 17 Network Address Translation (NAT) • Server: This type allows you to specify inside servers of different services behind the NAT to be accessible to the outside world although, it is highly recommended that you use the DMZ port for these servers instead. " Port numbers do not change for One-to-One and Many-One-to-One NAT mapping types. The following table summarizes the NAT mapping types.
Chapter 17 Network Address Translation (NAT) Selecting SUA means (latent) multiple WAN-to-LAN and WAN-to-DMZ address translation. That means that computers on your DMZ with public IP addresses will still have to undergo NAT mapping if you’re using SUA NAT mapping. If this is not your intention, then select Full Feature NAT and don’t configure NAT mapping rules to those computers with public IP addresses on the DMZ. 17.3 NAT Overview Screen Click ADVANCED > NAT to open the NAT Overview screen.

Chapter 17 Network Address Translation (NAT) " If you do not assign a Default Server IP address, the ZyWALL discards all packets received for ports that are not specified here or in the remote management setup. 17.5.2 Port Forwarding: Services and Port Numbers Use the Port Forwarding screen to forward incoming service requests to the server(s) on your local network. See Appendix D on page 653 for a list of commonly used services and port numbers.
Chapter 17 Network Address Translation (NAT) The following example has two web servers on a LAN. Server A uses IP address 192.168.1.33 and server B uses 192.168.1.34. Both servers use port 80. The letters a.b.c.d represent the WAN port’s IP address. The ZyWALL translates port 8080 of traffic received on the WAN port (IP address a.b.c.d) to port 80 and sends it to server A (IP address 192.168.1.33). The ZyWALL also translates port 8100 of traffic received on the WAN port (also IP address a.b.c.
Chapter 17 Network Address Translation (NAT) Figure 223 ADVANCED > NAT > Port Forwarding The following table describes the labels in this screen.

A default server receives packets from ports that are not specified in this screen.
Chapter 17 Network Address Translation (NAT) 17.7 Port Triggering Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address.

CHAPTER 18 Static Route This chapter shows you how to configure static routes for your ZyWALL. 18.1 IP Static Route The ZyWALL usually uses the default gateway to route outbound traffic from local computers to the Internet. To have the ZyWALL send data to devices not reachable through the default gateway, use static routes. For example, the next figure shows a computer (A) connected to the ZyWALL’s LAN interface. The ZyWALL routes most traffic from A to the Internet through the default gateway (R1).
Chapter 18 Static Route 18.2 IP Static Route Click ADVANCED > STATIC ROUTE to open the IP Static Route screen (some of the screen’s blank rows are not shown). The first static route entry is for the default WAN route. You cannot modify or delete a static default route. The default route is disabled after you change the static WAN IP address to a dynamic WAN IP address.

CHAPTER 19 Bandwidth Management This chapter describes the functions and configuration of bandwidth management with multiple levels of sub-classes. 19.1 Bandwidth Management Overview Bandwidth management allows you to allocate an interface’s outgoing capacity to specific types of traffic. It can also help you make sure that the ZyWALL forwards certain types of traffic (especially real-time applications) with minimum delay.
Chapter 19 Bandwidth Management 19.3 Proportional Bandwidth Allocation Bandwidth management allows you to define how much bandwidth each class gets; however, the actual bandwidth allotted to each class decreases or increases in proportion to actual available bandwidth. 19.4 Application-based Bandwidth Management You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, Email and Video for example). 19.
Chapter 19 Bandwidth Management Table 102 Application and Subnet-based Bandwidth Management Example TRAFFIC TYPE FROM SUBNET A FROM SUBNET B E-mail 64 Kbps 64 Kbps Video 64 Kbps 64 Kbps 19.7 Scheduler The scheduler divides up an interface’s bandwidth among the bandwidth classes. The ZyWALL has two types of scheduler: fairness-based and priority-based. 19.7.
Chapter 19 Bandwidth Management 2 Do not enable the interface’s Maximize Bandwidth Usage option. 3 Do not enable bandwidth borrowing on the sub-classes that have the root class as their parent (see Section 19.8 on page 355). 19.7.5 Maximize Bandwidth Usage Example Here is an example of a ZyWALL that has maximize bandwidth usage enabled on an interface. The following table shows each bandwidth class’s bandwidth budget. The classes are set up based on subnets. The interface is set to 10240 kbps.
Chapter 19 Bandwidth Management 19.7.5.2 Fairness-based Allotment of Unused and Unbudgeted Bandwidth The following table shows the amount of bandwidth that each class gets. Table 105 Fairness-based Allotment of Unused and Unbudgeted Bandwidth Example BANDWIDTH CLASSES AND ALLOTMENTS Root Class: 10240 kbps Administration: 1024 kbps Sales: 3072 kbps Marketing: 3072 kbps Research: 3072 kbps Suppose that all of the classes except for the administration class need more bandwidth.
Chapter 19 Bandwidth Management Refer to the product specifications in the appendix to see how many class levels you can configure on your ZyWALL. Table 106 Bandwidth Borrowing Example BANDWIDTH CLASSES AND BANDWIDTH BORROWING SETTINGS Root Class: Administration: Borrowing Enabled Sales: Borrowing Disabled Marketing: Borrowing Enabled Research: Borrowing Enabled • The Administration class can borrow unused bandwidth from the Root class because the Administration class has bandwidth borrowing enabled.
Chapter 19 Bandwidth Management If you use VoIP and NetMeeting at the same time, the device allocates up to 500 Kbps of bandwidth to each of them before it allocates any bandwidth to FTP. As a result, FTP can only use bandwidth when VoIP and NetMeeting do not use all of their allocated bandwidth. Suppose you try to browse the web too. In this case, VoIP, NetMeeting and FTP all have higher priority, so they get to use the bandwidth first.
Chapter 19 Bandwidth Management Table 108 ADVANCED > BW MGMT > Summary (continued) LABEL DESCRIPTION Scheduler Select either Priority-Based or Fairness-Based from the drop-down menu to control the traffic flow. Select Priority-Based to give preference to bandwidth classes with higher priorities. Select Fairness-Based to treat all bandwidth classes equally. See Section 19.7 on page 353.

CHAPTER 20 DNS This chapter shows you how to configure the DNS screens. 20.1 DNS Overview DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The ZyWALL uses a system DNS server (in the order you specify in the DNS System screen) to resolve domain names, for example, VPN, DDNS and the time server. 20.
Chapter 20 DNS 20.4 Address Record An address record contains the mapping of a fully qualified domain name (FQDN) to an IP address. An FQDN consists of a host and domain name and includes the top-level domain. For example, www.zyxel.com.tw is a fully qualified domain name, where “www” is the host, “zyxel” is the second-level domain, and “com.tw” is the top level domain. mail.myZyXEL.com.tw is also a FQDN, where "mail" is the host, "myZyXEL" is the secondlevel domain, and "com.tw" is the top level domain.
Chapter 20 DNS Figure 235 Private DNS Server Example " If you do not specify an Intranet DNS server on the remote network, then the VPN host must use IP addresses to access the computers on the remote private network. 20.6 System Screen Click ADVANCED > DNS to display the following screen. Use this screen to configure your ZyWALL’s DNS address and name server records.
Chapter 20 DNS The following table describes the labels in this screen. Table 114 ADVANCED > DNS > System DNS LABEL DESCRIPTION Address Record An address record specifies the mapping of a fully qualified domain name (FQDN) to an IP address. An FQDN consists of a host and domain name and includes the top-level domain. For example, www.zyxel.com.tw is a fully qualified domain name, where “www” is the host, “zyxel” is the second-level domain, and “com.tw” is the top level domain.
Chapter 20 DNS An address record contains the mapping of a fully qualified domain name (FQDN) to an IP address. Configure address records about the ZyWALL itself or another device to keep a record of DNS names and addresses that people on your network may use frequently. If the ZyWALL receives a DNS query for an FQDN for which the ZyWALL has an address record, the ZyWALL can send the IP address in a DNS response without having to query a DNS name server. See Section 20.
Chapter 20 DNS Figure 238 ADVANCED > DNS > Insert (Name Server Record) The following table describes the labels in this screen. Table 116 ADVANCED > DNS > Insert (Name Server Record) 370 LABEL DESCRIPTION Domain Zone This field is optional. A domain zone is a fully qualified domain name without the host. For example, zyxel.com.tw is the domain zone for the www.zyxel.com.tw fully qualified domain name. For example, whenever the ZyWALL receives needs to resolve a zyxel.com.
Chapter 20 DNS 20.7 DNS Cache DNS cache is the temporary storage area where a router stores responses from DNS servers. When the ZyWALL receives a positive or negative response for a DNS query, it records the response in the DNS cache. A positive response means that the ZyWALL received the IP address for a domain name that it checked with a DNS server within the five second DNS timeout period.
Chapter 20 DNS The following table describes the labels in this screen. Table 117 ADVANCED > DNS > Cache LABEL DESCRIPTION DNS Cache Setup Cache Positive DNS Resolutions Select the check box to record the positive DNS resolutions in the cache. Caching positive DNS resolutions helps speed up the ZyWALL’s processing of commonly queried domain names and reduces the amount of traffic that the ZyWALL sends out to the WAN.

CHAPTER 21 Remote Management This chapter provides information on the Remote Management screens. 21.1 Remote Management Overview Remote management allows you to determine which services/protocols can access which ZyWALL interface (if any) from which computers. The following figure shows secure and insecure management of the ZyWALL coming in from the WAN. HTTPS and SSH access are secure. HTTP and Telnet access are not secure.
Chapter 21 Remote Management 3 Telnet 4 HTTPS and HTTP 21.1.1 Remote Management Limitations Remote management does not work when: 1 You have not enabled that service on the interface in the corresponding remote management screen. 2 You have disabled that service in one of the remote management screens. 3 The IP address in the Secure Client IP Address field does not match the client IP address. If it does not match, the ZyWALL will disconnect the session immediately.
Chapter 21 Remote Management 1 HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the ZyWALL’s WS (web server). 2 HTTP connection requests from a web browser go to port 80 (by default) on the ZyWALL’s WS (web server). Figure 243 HTTPS Implementation " If you disable the HTTP service in the REMOTE MGMT WWW screen, then the ZyWALL blocks all HTTP connection attempts. 21.3 WWW Configuration Click ADVANCED > REMOTE MGMT to open the WWW screen.

Chapter 21 Remote Management 21.5 SSH You can use SSH (Secure SHell) to securely access the ZyWALL’s SMT or command line interface. Specify which interfaces allow SSH access and from which IP address the access can come. Unlike Telnet or FTP, which transmit data in plaintext (clear or unencrypted text), SSH is a secure communication protocol that combines authentication and data encryption to provide secure encrypted communication between two hosts over an unsecured network.
Chapter 21 Remote Management The SSH client sends a connection request to the SSH server. The server identifies itself with a host key. The client encrypts a randomly generated session key with the host key and server key and sends the result back to the server. The client automatically saves any new server public keys. In subsequent connections, the server public key is checked against the saved version on the client computer.

CHAPTER 24 ALG Screen This chapter covers how to use the ZyWALL’s ALG feature to allow certain applications to pass through the ZyWALL. 24.1 ALG Introduction An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the application layer. The ZyWALL can function as an ALG to allow certain NAT unfriendly applications (such as SIP) to operate properly through the ZyWALL.
Chapter 24 ALG Screen 24.2 FTP File Transfer Protocol (FTP) is an Internet file transfer service that operates on the Internet and over TCP/IP networks. A system running the FTP server accepts commands from a system running an FTP client. The service allows users to send commands to the server for uploading and downloading files. The FTP ALG allows TCP packets with a port 21 destination to pass through.
Chapter 24 ALG Screen • The ZyWALL can also apply bandwidth management to traffic that goes through the H.323 ALG. 24.5 SIP The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is used in VoIP (Voice over IP), the sending of voice signals over the Internet Protocol. SIP signaling is separate from the media for which it handles sessions.
Chapter 24 ALG Screen Figure 269 SIP ALG Example 24.5.3 SIP Signaling Session Timeout Most SIP clients have an “expire” mechanism indicating the lifetime of signaling sessions. The SIP user agent sends registration packets to the SIP server periodically and keeps the session alive in the ZyWALL. If the SIP client does not have this mechanism and makes no calls during the ZyWALL SIP timeout default (60 minutes), the ZyWALL SIP ALG drops any incoming calls after the timeout period. 24.5.

Chapter 25 Logs Screens 25.6 Syslog Logs There are two types of syslog: event logs and traffic logs. The device generates an event log when a system event occurs, for example, when a user logs in or the device is under attack. The device generates a traffic log when a "session" is terminated. A traffic log summarizes the session's type, when it started and stopped the amount of traffic that was sent and received and so on.

CHAPTER 26 Maintenance This chapter displays information on the maintenance screens. 26.1 Maintenance Overview The maintenance screens can help you view system information, upload new firmware, manage configuration and restart your ZyWALL. 26.2 General Setup and System Name General Setup contains administrative and system-related information. System Name is for identification purposes. However, because some ISPs check this name you should enter your computer's "Computer Name".
Chapter 26 Maintenance Figure 279 MAINTENANCE > General Setup The following table describes the labels in this screen. Table 160 MAINTENANCE > General Setup LABEL DESCRIPTION General Setup System Name Choose a descriptive name for identification purposes. It is recommended you enter your computer’s “Computer name” in this field. This name can be up to 30 alphanumeric characters long. Spaces are not allowed, but dashes “-” and underscores "_" are accepted.
Chapter 26 Maintenance Figure 280 MAINTENANCE > Password The following table describes the labels in this screen. Table 161 MAINTENANCE > Password LABEL DESCRIPTION Old Password Type the default password or the existing password you use to access the system in this field. If you forget the password, you may have to use the hardware RESET button. This restores the default password of 1234. New Password Type your new system password (up to 30 characters).
Chapter 26 Maintenance Figure 281 MAINTENANCE > Time and Date The following table describes the labels in this screen. Table 162 MAINTENANCE > Time and Date LABEL DESCRIPTION Current Time and Date Current Time This field displays the ZyWALL’s present time. Current Date This field displays the ZyWALL’s present date. Time and Date Setup 450 Manual Select this radio button to enter the time and date manually.
Chapter 26 Maintenance Table 162 MAINTENANCE > Time and Date (continued) LABEL DESCRIPTION Time Protocol Select the time service protocol that your time server uses. Not all time servers support all protocols, so you may have to check with your ISP/network administrator or use trial and error to find a protocol that works. The main difference between them is the format. Daytime (RFC 867) format is day/month/year/time zone of the server.
Chapter 26 Maintenance 26.5 Pre-defined NTP Time Server Pools When you turn on the ZyWALL for the first time, the date and time start at 2000-01-01 00:00:00. The ZyWALL then attempts to synchronize with an NTP time server from one of the 0.pool.ntp.org, 1.pool.ntp.org or 2.pool.ntp.org NTP time server pools. These are virtual clusters of time servers that use a round robin method to provide different NTP servers to clients.
Chapter 26 Maintenance Figure 283 Synchronization is Successful If the update was not successful, the following screen appears. Click Return to go back to the Time and Date screen. Figure 284 Synchronization Fail 26.6 Introduction To Transparent Bridging A transparent bridge is invisible to the operation of a network in that it does not modify the frames it forwards. The bridge checks the source address of incoming frames on the port and learns MAC addresses to associate with that port.
Chapter 26 Maintenance For example, if a bridge receives a frame via port 1 from host A (MAC address 00a0c5123478), the bridge associates host A with port 1. When the bridge receives another frame on one of its ports with destination address 00a0c5123478, it forwards the frame directly through port 1 after checking the internal table.
Chapter 26 Maintenance Figure 285 MAINTENANCE > Device Mode (Router Mode) The following table describes the labels in this screen. Table 164 MAINTENANCE > Device Mode (Router Mode) LABEL DESCRIPTION Current Device Mode Device Mode This displays whether the ZyWALL is functioning as a router or a bridge. Device Mode Setup Router When the ZyWALL is in router mode, there is no need to select or clear this radio button.
Chapter 26 Maintenance In bridge mode, the ZyWALL functions as a transparent firewall (also known as a bridge firewall). The ZyWALL bridges traffic traveling between the ZyWALL's interfaces and still filters and inspects packets. You do not need to change the configuration of your existing network. In bridge mode, the ZyWALL cannot get an IP address from a DHCP server. The LAN, WAN, DMZ and WLAN interfaces all have the same (static) IP address and subnet mask.
Chapter 26 Maintenance Table 165 MAINTENANCE > Device Mode (Bridge Mode) (continued) LABEL DESCRIPTION DHCP DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients (computers) to obtain TCP/IP configuration at startup from a server. Unless you are instructed by your ISP, leave the DHCP check box selected. Clear it to stop the ZyWALL from acting as a DHCP server. When configured as a server, the ZyWALL provides TCP/IP configuration for the clients.

Chapter 37 Introducing the ZyWALL Firewall Figure 366 Menu 21.2: Firewall Setup Menu 21.2 - Firewall Setup The firewall protects against Denial of Service (DoS) attacks when it is active. Your network is vulnerable to attacks when the firewall is turned off. Refer to the User's Guide for details about the firewall default policies. You may define additional policy rules or modify existing ones but please exercise extreme caution in doing so.
CHAPTER 38 Filter Configuration This chapter shows you how to create and apply filters. 38.1 Introduction to Filters Your ZyWALL uses filters to decide whether to allow passage of a data packet and/or to make a call. There are two types of filter applications: data filtering and call filtering. Filters are subdivided into device and protocol filters, which are discussed later. Data filtering screens the data to determine if the packet should be allowed to pass.
Chapter 38 Filter Configuration 38.1.1 The Filter Structure of the ZyWALL A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for NetBIOS, into a single set and give it a descriptive name. The ZyWALL allows you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system. You cannot mix device filter rules and protocol filter rules within the same set.
Chapter 38 Filter Configuration Figure 368 Filter Rule Process You can apply up to four filter sets to a particular port to block multiple types of packets. With each filter set having up to six rules, you can have a maximum of 24 rules active for a single port.
Chapter 38 Filter Configuration 38.2 Configuring a Filter Set The ZyWALL includes filtering for NetBIOS over TCP/IP packets by default. To configure another filter set, follow the procedure below. 1 Enter 21 in the main menu to open menu 21. Figure 369 Menu 21: Filter and Firewall Setup Menu 21 - Filter and Firewall Setup 1.

To speed up filtering, all rules in a filter set must be of the same class, i.e., protocol filters or generic filters.
Chapter 38 Filter Configuration The following table describes how to configure your TCP/IP filter rule. Table 204 Menu 21.1.1.1: TCP/IP Filter Rule FIELD DESCRIPTION Active Press [SPACE BAR] and then [ENTER] to select Yes to activate the filter rule or No to deactivate it. IP Protocol Protocol refers to the upper layer protocol, e.g., TCP is 6, UDP is 17 and ICMP is 1. Type a value between 0 and 255. A value of 0 matches ANY protocol.
Chapter 38 Filter Configuration The following figure illustrates the logic flow of an IP filter.
Chapter 38 Filter Configuration 38.2.3 Configuring a Generic Filter Rule This section shows you how to configure a generic filter rule. The purpose of generic rules is to allow you to filter non-IP packets. For IP, it is generally easier to use the IP rules directly. For generic rules, the ZyWALL treats a packet as a byte stream as opposed to an IP or IPX packet. You specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes.
Chapter 38 Filter Configuration Table 205 Generic Filter Rule Menu Fields FIELD DESCRIPTION More If Yes, a matching packet is passed to the next filter rule before an action is taken; else the packet is disposed of according to the action fields. If More is Yes, then Action Matched and Action Not Matched will be No. Log Select the logging option from the following: None - No packets will be logged. Action Matched - Only packets that match the rule parameters will be logged.

Chapter 38 Filter Configuration 38.5.1.1 When To Use Filtering 1 To block/allow LAN packets by their MAC addresses. 2 To block/allow special IP packets which are neither TCP nor UDP, nor ICMP packets. 3 To block/allow both inbound (WAN to LAN) and outbound (LAN to WAN) traffic between the specific inside host/network "A" and outside host/network "B". If the filter blocks the traffic from A to B, it also blocks the traffic from B to A.
Chapter 38 Filter Configuration " If you do not activate the firewall, it is advisable to apply filters. 38.6.1 Applying LAN Filters LAN traffic filter sets may be useful to block certain packets, reduce traffic and prevent security breaches. Go to menu 3.1 (shown next) and enter the number(s) of the filter set(s) that you want to apply as appropriate. You can choose up to four filter sets (from twelve) by entering their numbers separated by commas, e.g., 3, 4, 6, 11.

APPENDIX C IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix C IP Addresses and Subnetting Figure 461 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “subnetwork”. A subnet mask has 32 bits.
Appendix C IP Addresses and Subnetting Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Table 228 Subnet Masks BINARY DECIMAL 1ST OCTET 2ND OCTET 3RD OCTET 4TH OCTET 8-bit mask 11111111 00000000 00000000 00000000 255.0.0.0 16-bit mask 11111111 11111111 00000000 00000000 255.255.0.0 24-bit mask 11111111 11111111 11111111 00000000 255.255.255.
