76 CHAPTER 5: CONFIGURING THE ROUTER Virtual Servers The Virtual servers feature allows you to route external (Internet) calls for services such as a web server (port 80), FTP server (Port 21), or other applications through your Router to your internal network. Since your internal computers are protected by a firewall, machines from the Internet cannot get to them because they cannot be 'seen'.
Firewall 77 3 Specify the public port that will be seen by clients on the Internet, and the LAN port which the traffic will be routed to. 4 You can enable or disable each Virtual Server entry by checking or unchecking the appropriate Enabled checkbox. 5 Click Apply to save the changes for each Virtual Server entry. DMZ If you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access.
78 CHAPTER 5: CONFIGURING THE ROUTER PC Privileges The Router can be configured to restrict access to the Internet, email or other network services at specific days and times. Restriction can be set for a single computer, a range of computers, or multiple computers. You can define the traffic type permitted or not-permitted to the Internet.
Firewall 79 Figure 64 PC Privileges Add PC Screen 1 Enter a description in the Client PC Description field, and the IP address or IP address range into the Client PC IP Address fields. 2 To bypass the URL Filter and Content Filter, check the corresponding Bypass checkbox. If you check the two options: Bypass URL Filter, and Bypass Content Filter, then the Web sites and keywords defined in this screen will not be filtered out. 3 Select the services to be blocked.
80 CHAPTER 5: CONFIGURING THE ROUTER Schedule Rule The Router can be configured to restrict access to the Internet, email or other network services at specific days and times. Define the time in this screen, and define the rules in the PC Privileges screen (see page 78). Figure 65 Schedule Rule Screen 1 Click Add Rule to add a schedule rule (refer to Figure 66). Figure 66 Add Schedule Rule Screen 2 Enter a name and comment for the schedule rule in the Name and Comment fields.
Firewall URL Filter 81 To configure the URL filter feature, use the table on the URL Filter screen to specify the Web sites (www.somesite.com) and/or keywords you want to filter on your network. For example, entering a keyword of xxx would block access to any URL that contains the string xxx. Figure 67 URL Filter Screen 1 Check the Enable URL Filtering Function checkbox. The rule table will appear. 2 Enter the URL address or keywords in the URL/Keyword field.
82 CHAPTER 5: CONFIGURING THE ROUTER Advanced The Advanced section allows you to set additional parameter details for the Router. You can configure: Security ■ Security ■ VLAN ■ Static Routes ■ RIP ■ DDNS ■ SNMP ■ Syslog ■ Proxy Arp ■ QoS Settings Use the Security screen to set the advanced security settings for the Router.
Advanced ■ 83 NAT — Before you enable NAT (Network Address Translation), make sure you have changed the administrator password. NAT is the method by which the Router shares the single IP address assigned by your ISP with the computers on your network. This function should only be disabled by advanced users, and if your ISP assigns you multiple IP addresses or you need NAT disabled for an advanced system configuration.
84 CHAPTER 5: CONFIGURING THE ROUTER ■ MSS Clamping — You might not be able to browse some Web sites or to send email messages that contain attachments from an Internet Connection Sharing client computer if your outbound connection is through a Windows XP-based Internet Connection Sharing host computer that uses Point-to-Point Protocol over Ethernet (PPPoE).
Advanced VLAN 85 The VLAN screen allows you to setup VLAN groups. Figure 69 VLAN Screen Static Routes You can configure static routes in this screen. Figure 70 Static Routes Screen To add a static route entry to the table, click Add (see Figure 71). To change an existing entry, click Edit. To delete an entry, click Delete.
86 CHAPTER 5: CONFIGURING THE ROUTER Figure 71 Add Static Route Screen Enter the following information: ■ Index — the index of the entry. ■ Network Address — the network address of the static route. ■ Subnet Mask — the subnet mask of the route. A network address of 0.0.0.0 and a subnet mask of 0.0.0.0 indicates the default route. ■ Gateway — the router used to route data to the network specified by the network address. ■ Interface — select the interface.
Advanced RIP 87 RIP (Routing Information Protocol) - RIP allows the network administrator to set up routing information on one RIP-enabled device and send that information to all RIP-enabled devices on the network. Figure 72 RIP Parameter Screen You can set up RIP independently on both LAN and WAN interfaces. 1 Check the Enable RIP checkbox. 2 Check the Enable Auto summary checkbox. Auto summarization sends simplified routing data to other RIP-enabled devices rather than full routing data.
88 CHAPTER 5: CONFIGURING THE ROUTER 5 Use the Poison Reverse drop-down menu to enable or disable Poison Reverse on the Router. Enabling Poison Reverse on your Router allows it to indicate to other RIP-enabled devices that they have both routes that point to each other, preventing data loops. 6 Use the Authentication Required field to choose the mode of authentication: ■ None — Switches off authentication on the specified interface.
Advanced DDNS 89 The Router provides a list of dynamic DNS providers for you to choose from. Dynamic Domain Name Server (DDNS) enables you to map a static domain name to a dynamic IP address. Before you set up DDNS, you must obtain an account, password or key and static domain name from your DDNS provider. The Router supports five DDNS providers: ■ DynDNS.org ■ TZO.com ■ Dt DNS.com ■ No-IP.com ■ Zoneedit.com Figure 73 Dynamic Domain Name Server (DDNS) Screen 1 Check Enable DDNS.
90 CHAPTER 5: CONFIGURING THE ROUTER SNMP SNMP (Simple Network Management Protocol) allows remote management of your Router by a PC that has an SNMP management agent installed. Check the Enable SNMP box, the table will appear. Figure 74 SNMP Screen To Configure SNMP Community: 1 In the Community column, enter the name of the SNMP communication channel. Your SNMP management agent needs to be configured with this name so that it can communicate with your Router.
Advanced 91 You can configure your Router to send status messages to the SNMP management agent if a problem occurs on the network. To configure SNMP traps: 1 In the IP Address field, enter the IP address of the PC to which you want your Router to send status messages. 2 In the Community field, enter the name of the SNMP communication channel to which you want your Router to send status messages. 3 Set the Version field to match the version of trap messaging that your SNMP management agent supports.
92 CHAPTER 5: CONFIGURING THE ROUTER Proxy ARP Proxy ARP is the technique in which one host, usually a Router, answers ARP requests intended for another machine. By “faking” its identity, the Router accepts responsibility for routing packets to the “real” or intended destination. This heightens the security for your network. Figure 76 Proxy ARP Screen 1 Check the Enable ProxyARP box. 2 Enter the corresponding IP address in the IP Address From and IP Address To fields. 3 Click Apply.
Advanced QoS Settings 93 The QoS (Quality of Service) function allows you to differentiate your network traffic and provide it with high-priority forwarding service. The bandwidth gap between LAN and WAN may significantly degrade performance of critical network applications, such as VoIP, gaming, and VPN. This QoS function allows you to classify traffic of applications and provides them with differentiated services (Diffserv). Figure 77 QoS Settings Screen 1 Check the Enable QoS box.
94 VPN CHAPTER 5: CONFIGURING THE ROUTER The Router has a Virtual Private Network (VPN) feature that provides a secure link between remote users and the corporate network by establishing an authenticated and encrypted tunnel for passing secure data over the Internet. The Router supports three modes of VPN operation: ■ IPsec (IP Security) — provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication.
VPN 1 Check the Enable IPsec box. Figure 78 VPN Screen 2 Enter the Local ID Name of your VPN. 3 Click Add to create a new entry.
96 CHAPTER 5: CONFIGURING THE ROUTER On the VPN Tunnel Configuration screen, 1 Select IPSec as the VPN Tunnel Type. 2 Enter a descriptive name for the tunnel in the Tunnel Name field. 3 Remote VPN Gateway - select IP address, and then enter the IP address in the IP Address/Host Name field. If you select ANY, then it would be no need to enter the IP address, as any remote server can be used. 4 At the Remote Party ID drop-down list, select either IP_IPV4_ADDR or ID_USER_FQDN.
VPN Enter the following Phase II IPSec Parameters: ■ Authentication Algorithm ■ Encrypt Algorithm ■ Key lifetime ■ PFS ■ Diffie-Hellman Group ■ IKE Keep Alive - 97
98 CHAPTER 5: CONFIGURING THE ROUTER System Tools Restart Router These screens allow you to manage different parameters of the Router and perform certain administrative functions. Sometimes it may be necessary to restart (or reboot) the Router. Restarting the Router from this screen will not delete any of your configuration settings. Click the Restart the Router button to restart the Router.
System Tools Upgrade 99 ■ Backup Configuration — You can save your current configuration by clicking the Backup button.

100 CHAPTER 5: CONFIGURING THE ROUTER Time Zone You can set the time settings for the Router on this screen. Figure 83 Time Zone Screen The Router keeps time by connecting to a Network Time Protocol (NTP) server. This allows the Router to synchronize the system clock to the Internet. The synchronized clock in the Router is used to record the security log and control client filtering. Select the time zone that you reside in.
System Tools Ping 101 The ping tool is used to test if the network is working properly. Figure 84 Ping Screen 1 Enter the IP address or domain name in the IP Address or Domain Name field, and click Ping. 2 Select from the Number of times to Ping drop-down menu. 3 The Router keeps a log of the ping test, click Clear Log to delete the records.
102 CHAPTER 5: CONFIGURING THE ROUTER Traceroute Traceroute is the program that shows you the route over the network between two systems, listing all the intermediate routers a connection must pass through to get to its destination. It can help you determine why your connections to a given server might be poor, and can often help you figure out where exactly the problem is.
System Tools DNS Lookup 103 DNS Lookup is the process of resolving an IP address (i.e. 192.168.11.137) to a host name (i.e. xxxcompany.net). Figure 86 DNS Lookup Screen 1 Enter the IP address or domain name in the IP Address or Domain Name field, and click Dns lookup. 2 The Router keeps a log of the DNS lookup test, click Clear Log to delete the records.
104 CHAPTER 5: CONFIGURING THE ROUTER Status and Logs Status You can use the Status Screen to view version numbers for your Router’s software and hardware and check the status of connections to WAN, LAN and WLAN interfaces.

Wireless Networking ■ Ensure that you have an 802.11b or 802.11g or 802.
110 CHAPTER 6: TROUBLESHOOTING Additionally consider moving the wireless computer closer to the Router to confirm that the building structure or fittings are not adversely affecting the connectivity. If this resolves the problem consider relocating the wireless computer or the Router, or trying a different channel on the Router. ■ Sources of interference: The 2.4Ghz ISM band is used for 802.11b and 802.11g.
Recovering from Corrupted Software Recovering from Corrupted Software 111 If the system software has become corrupted, the Router will enter a “recovery” state; DHCP is enabled, and the LAN IP address is set to 192.168.1.1. Follow the instructions below to upload a new copy of the system software to a Router unit in this state. Ensure that one of your computers has a copy of the new software image file stored on its hard disk or available on CD-ROM. Check your ISP for the latest version firmware.
112 CHAPTER 6: TROUBLESHOOTING Frequently Asked Questions How do I reset the Router to Factory Defaults? See Forgotten Password and Reset to Factory Defaults on page 108. How many computers on the LAN does the Router support? A maximum of 253 computers on the LAN are supported. How many wireless clients does the Router support? A maximum of 128 wireless clients are supported. There are only 4 LAN ports on the Router.
A IP ADDRESSING The Internet Protocol Suite The Internet Protocol suite consists of a well-defined set of communications protocols and several standard application protocols. Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the most widely known and is a combination of two of the protocols (IP and TCP) working together.
114 APPENDIX A: IP ADDRESSING For your network to work correctly, all devices on the network must have: ■ The same sub-network address. ■ The same subnet mask. The only value that will be different is the specific host device number. This value must always be unique. An example IP address is ‘192.168.100.8’. However, the size of the network determines the structure of this IP address. In using the Router, you will probably only encounter two types of IP address and subnet mask structures.
How does a Device Obtain an IP Address and Subnet Mask? 115 This type of IP Address operates on a subnet mask of ‘255.255.0.0’. See Table 4 for an example about how a network (only four computers represented) and a Router might be configured. Table 4 IP Addressing and Subnet Masking How does a Device Obtain an IP Address and Subnet Mask? DHCP Addressing Device IP Address Subnet Mask PC 1 192.168.100.8 255.255.0.0 PC 2 192.168.201.30 255.255.0.0 PC 3 192.168.113.155 255.255.0.0 PC 4 192.
116 APPENDIX A: IP ADDRESSING an IP address at random from the industry standard subnet of 169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate themselves the same address, the conflict is detected and one of the devices allocates itself a new address. Automatic IP addressing support was introduced by Microsoft in the Windows 98 operating system and is also supported in Windows 2000 and Windows XP.
