Configuring the Firewall
Your N1 Vision 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.
Disabling the firewall protection will not leave your network completely
vulnerable to hacker attacks, but it is recommended that you leave the
firewall enabled.
