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.
