Belkin F5D9630-4 user manual Configuring the Firewall, Configuring Internal Forwarding Settings

Using the Web-Based Advanced User Interface

Configuring the Firewall

Your Router is equipped with a firewall that will protect your network from a wide array of common hacker attacks including:

•IP Spoofing

•Land Attack Ping of Death (PoD)

•Denial of Service (DoS)

•IP with zero length

•Smurf Attack

•TCP Null Scan

•SYN flood

•UDP flooding

•Tear Drop Attack

•ICMP defect

•RIP defect

•Fragment flooding

The firewall also masks common ports that are frequently used to attack networks. These ports appear to be “stealth” meaning that for all intents and purposes, they do not exist to a would-be hacker. You can turn the firewall function off if needed; however, it is recommended that you leave the firewall enabled. Disabling the firewall protection will not leave your network completely vulnerable to hacker attacks, but it is recommended that you leave the firewall enabled.

Configuring Internal Forwarding Settings

The Virtual Servers function will allow 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.
