[. . . ] The server computer in the LAN that will be providing the virtual services Virtual Server IP For example, if you have an FTP server on the LAN side you wanted Internet users to access, suppose the PC has a local IP address of 192. 168. 1. 1, you would use the following virtual server settings: ¾ ¾ ¾ ¾ Protocol: TCP Port: 21 (FTP uses port 21) Virtual Server IP: 192. 168. 1. 1 Enable: enable 36 GN-BR33V-RH 2. 4GHz AirCruiser Extreme N Wireless Router The PPPoE Unnumber Tab Advanced feature of the GN-BR33V-RH is that it supports services that offer multiple global IP addresses, with each IP address requires its own setting. The GN-BR33V-RH has an IP allocation scheme capable of directly assigning global IP to LAN clients. You can only take advantage of this feature if your ISP service packages will provide you with a range of valid “Global IP”. (For example 61. 222. 10. 1 ~ 61. 222. 10. 7) These seven addresses can be individually configured. Global IP Protocol Port An IP within the range of IP’s assigned to you by your ISP The protocol used for the Unnumbered service The port number of the service used by the LAN side Virtual Server IP The computer on the LAN that will be providing the Unnumbered virtual services Example: Taking the IP address of 192. 168. 1. 1 of a PC connected to the GN-BR33V-RH for example would use the following settings: ¾ ¾ ¾ ¾ Global IP: 61. 222. 10. 2 Protocol: TCP Port: 21 Virtual Server IP: 192. 168. 1. 1 37 GN-BR33V-RH 2. 4GHz AirCruiser Extreme N Wireless Router ¾ Enable: enable The Global IP 61. 222. 10. 2 is now directly assigned to the FTP server at the IP address 192. 168. 1. 1 located within the GN-BR33V-RH’s LAN. The Firewall Rule Screen The Firewall Rule screen displays your network security settings. Use this screen to create network security policies to prevent unauthorized access to your network. The Security Configuration Tab Select security configuration options from this page including Security One-Touch Setting, Stealth Mode and Unlawful Computer Access Detection. You can select with one click a ‘High” “Medium” or “Low (off)” level of Security. You can fine tune your security level settings with the One-touch Settings section. Just check /uncheck the boxes to include/remove that particular setting. When any item in Security One-touch setting combined with “Stateful Packet Inspection is used” under the Unlawful Computer Access Detection group are checked, the URL Blocking feature becomes unavailable. 38 GN-BR33V-RH 2. 4GHz AirCruiser Extreme N Wireless Router The VPN Pass Through Tab A Virtual Private Network (VPN) is a type of secured private network connection, built upon publicly-accessible infrastructure such as the Internet. They usually provide connectivity to various devices behind a gateway or firewall. The GN-BR33V-RH supports Internet-industry standard technologies to provide open and interoperable VPN solutions, including Internet Protocol Security (IPSec), Layer 2 Tunneling Protocol (L2TP) and Point-to-Point Tunneling Protocol (PPTP). PPTP Pass Through setting Point-to-Point Tunneling Protocol (PPTP) allows you to establish a connection to an enterprise network. To allow PPTP tunnels to pass through the Router, click Enable and key in the Router’s IP address. IPSec Pass Through setting IP Security (IPSec) provides authentication and encryption. Since it is mainly a Layer 3 technology, it can secure all data on the network. To allow IPSec tunnels to pass through the Router, click Enable and key in the Router’s IP address. L2TP Pass Through setting Layer 2 Tunneling Protocol (L2TP) is an extension of the Point-to-Point Tunneling Protocol and is also used to establish virtual private networks. To allow L2TP tunnels to pass through the Router, click Enable, and key in the Router’s IP address. 39 GN-BR33V-RH 2. 4GHz AirCruiser Extreme N Wireless Router The Static Rule Tab The Static Rule screen allows you to manually edit the firewall rule table, thereby helping to protect your network from external attacks as well as provide a method to restrict Internet access to users on your network. Additionally, it can filter out specific packets which are used by hackers to trigger the Router to establish an outgoing connection. To edit the current settings, click the Add button. The following screen will appear. 40 GN-BR33V-RH 2. 4GHz AirCruiser Extreme N Wireless Router Rule Number (No. ) Enter a number for the rule between 1 and 64. Rules are ranked in priority based on their number in descending order, so that rule 1 is given the highest priority and rule 64 the lowest priority. You can specify the Router to drop (or accept) all packets which meets the Rule criteria. Direction Specify the packet flow direction according to data filtering rule.
