The FriendlyNET FR3000 series routers have a built-in firewall that is automatically activated when you connect your computers. It cannot be deactivated, but it features a high level of customization. If you are not familiar with TCP/IP, NAT, and UDP ports, you may wish to view the following FAQ items before you configure your firewall: "What is an IP Address?", "What is the difference between a hub, switch and router?", and "What is a firewall and how does it work?".

1. Accessing the Advanced Security menu:

1. Start your web browser. Type http://192.168.123.254 Into your browser's address or location field and press Enter.
2. In a few moments you'll see the Login screen for the router. Enter admin (the default password) and click Log in.
3. Click the Advanced button from the top of the page.
4. Scroll down until you see Distributed Servers menu. It should look similar to this:

Distributed Servers Setup Port ID Service Port Server IP Enable   1 192.168.100.   2 192.168.100.   3 192.168.100.   4 192.168.100.   5 192.168.100.   6 192.168.100.   7 192.168.100.   8 192.168.100.

2. Configuring Distributed Servers:

Distributed Servers is one of the most powerful features of the FriendlyNET Cable/DSL router. It is used to redirect inbound WAN traffic to specific computers on the LAN (and computers connected to the router's LAN ports). In other words, if you have an FTP server, Web server, POP3 server, and an Email server, you can use the Distributed Servers option to redirect web, email, ftp and POP3 email to the correct computers using UDP ports. This can keep your computers safe and stable by filtering out traffic not meant for each machine's type of service.

If you have a growing Internet business and a static IP address, then use the router's Distributed Servers feature to handle network requests by up to eight separate servers. Although each server can handle multiple network services, only one server can be assigned to each network service. To quickly enable popular services, use the "expression builder" at the bottom of the screen.

When you are done setting up your distributed servers, click the Apply New Distributed Server Settings button. Be sure to check the Enable checkbox.
