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
• SYN flood
• Land Attack
• UDP flooding
• Ping of Death (PoD)
• Tear Drop Attack
• Denial of Service (DoS)
• ICMP defect
• IP with zero length
• RIP defect
• Smurf Attack
• Fragment flooding
• TCP Null Scan
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.
