C HAPT ER 8 LAN 8.1 Overview This chapter describes how to configure LAN settings. A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server, manage IP addresses, and partition your physical network into logical networks.
Chapter 8 LAN Figure 69 LAN and WAN IP Addresses The LAN parameters of the NBG-418N v2 are preset in the factory with the following values: • IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) • DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded Web Configurator help regarding what fields need to be configured. 8.2.
Chapter 8 LAN important because without it, you must know the IP address of a computer before you can access it. The NBG-418N v2 can get the DNS server addresses in the following ways. 1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the Wizard and/or WAN > Internet Connection screen.

C HAPTER 10 Network Address Translation 10.1 Overview This chapter discusses how to configure NAT on the NBG-418N v2. 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. Each packet has two addresses – a source address and a destination address.
Chapter 10 Network Address Translation 10.2 What You Can Do • Use the General screen to enable NAT and set a default server (Section 10.3 on page 106). • Use the Application screen to change your NBG-418N v2’s port forwarding settings (Section 10.4 on page 107). • Use the Port Triggering screen to change your NBG-418N v2’s port trigger settings (Section 10.5 on page 108). 10.2.1 What You Need To Know The following terms and concepts may help as you read through this chapter.
Chapter 10 Network Address Translation The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection.
Chapter 10 Network Address Translation The following table describes the labels in this screen. Table 48 Network > NAT > General LABEL DESCRIPTION NAT Setup Network Address Translation Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).

Chapter 10 Network Address Translation 10.6.2 NAT Port Forwarding Example Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. Figure 79 Multiple Servers Behind NAT Example 10.6.
Chapter 10 Network Address Translation Figure 80 Trigger Port Forwarding Process: Example Jane’s computer Real Audio Server Port 7070 1 Jane requests a file from the Real Audio server (port 7070). 2 Port 7070 is a “trigger” port and causes the NBG-418N v2 to record Jane’s computer IP address. The NBG-418N v2 associates Jane's computer IP address with the "incoming" port range of 69707170. 3 The Real Audio server responds using a port number ranging between 6970-7170.
C HAPTER 11 Dynamic DNS 11.1 Overview Dynamic Domain Name Service (DDNS) services let you use a fixed domain name with a dynamic IP address. Users can always use the same domain name instead of a different dynamic IP address that changes each time to connect to the NBG-418N v2 or a server in your network. Note: The NBG-418N v2 must have a public global IP address and you should have your registered DDNS account information on hand. 11.

C HAPTER 12 Static Route 12.1 Overview This chapter shows you how to configure static routes for your NBG-418N v2. The NBG-418N v2 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the NBG-418N v2 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 NBG-418N v2’s LAN interface.
Chapter 12 Static Route Figure 83 Network > Static Route The following table describes the labels in this screen. Table 52 Network > Static Route LABEL DESCRIPTION Enable Select this to enable this rule. Destination Enter the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.
C HAPTER 13 Firewall 13.1 Overview Use these screens to enable and configure the firewall that protects your NBG-418N v2 and your LAN from unwanted or malicious traffic. Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall: • allows traffic that originates from your LAN computers to go to all of the networks. • blocks traffic that originates on the other networks from going to the LAN.
Chapter 13 Firewall 13.3 What You Need To Know The NBG-418N v2’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks. 13.3.1 About the NBG-418N v2 Firewall The NBG-418N v2 firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Firewall and then click the Enable Firewall check box).

Chapter 13 Firewall The following table describes the labels in this screen. Table 54 Security > Firewall > Services LABEL DESCRIPTION ICMP Internet Control Message Protocol (ICMP) is a message control and error-reporting protocol between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and directly apparent to the application user.
C HAPTER 14 Content Filter 14.1 Overview Content filter allows you to block specific URLs. The NBG-418N v2 checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking. The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw. The file path is the characters that come after the first slash in the URL.
Chapter 14 Content Filter Figure 87 Security > Content Filter > Filter The following table describes the labels in this screen. Table 55 Security > Content Filter > Filter LABEL DESCRIPTION Enable URL Keyword Blocking The NBG-418N v2 can block Web sites with URLs that contain certain keywords in the domain name or IP address. For example, if the keyword "bad" was enabled, all sites containing this keyword in the domain name or IP address will be blocked, e.g., URL http:/ /www.website.com/bad.
C HAPTER 15 Remote Management 15.1 Overview This chapter provides information on the Remote Management screen. Note: When you configure remote management to allow management from the WAN, you still need to configure a firewall rule to allow access. See the firewall chapters for details on configuring firewall rules.
Chapter 15 Remote Management 15.1.1 Remote Management Limitations Remote management over WAN will not work when: 1 You have disabled that service in the remote management screen. 2 The IP address in the Secured Client WAN IP Address field does not match the client IP address.

A PPENDIX A 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 A IP Addresses and Subnetting Figure 118 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 “sub-network”. A subnet mask has 32 bits.
Appendix A 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 67 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.

Appendix A IP Addresses and Subnetting Figure 120 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address.

Appendix A IP Addresses and Subnetting Configuring IP Addresses 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.
Appendix A IP Addresses and Subnetting Conflicting Computer IP Addresses Example More than one device can not use the same IP address. In the following example computer A has a static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by assigning a different static IP address to computer A or setting computer A to obtain an IP address automatically.

A PPENDIX D Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Appendix D Wireless LANs Figure 144 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood.
Appendix D Wireless LANs Figure 145 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.
Appendix D Wireless LANs Figure 146 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations. RTS/CTS is designed to prevent collisions due to hidden nodes.
Appendix D Wireless LANs Preamble Type Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet. Short preamble increases performance as less time sending preamble means more time for sending data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short preamble.
Appendix D Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your NBG-418N v2. Table 78 Wireless Security Levels SECURITY LEVEL Least Secure SECURITY TYPE Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802.
Appendix D Wireless LANs RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server. Types of RADIUS Messages The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication: • Access-Request Sent by an access point requesting authentication. • Access-Reject Sent by a RADIUS server rejecting access. • Access-Accept Sent by a RADIUS server allowing access.
Appendix D Wireless LANs EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client. The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses.
Appendix D Wireless LANs If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen. You may still configure and store keys, but they will not be used while dynamic WEP is enabled. Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption.
Appendix D Wireless LANs called Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is never used twice.
Appendix D Wireless LANs WPA(2) with RADIUS Application Example To set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server.
Appendix D Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 148 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type.
Appendix D Wireless LANs Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz or 5GHz is needed to communicate efficiently in a wireless LAN Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area. Antenna Gain Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width.
Appendix D Wireless LANs For directional antennas, point the antenna in the direction of the desired coverage area.
