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
