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
essentially 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.

Virtual Servers
Virtual servers 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. Since your internal
computers are protected by a firewall, machines from the Internet cannot
get to them because they cannot be "seen". If you need to configure the
virtual server function for a specific application, you will need to contact
the application vendor to find out which port settings you need. You can
manually input this port information into the Router.
