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
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.
