PlugLink 9950 Cable/ DSL Router PL9950-BBR

Chapter 10

Configuring the Firewall

Your 9950 Cable/ DSL 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

UDP Flooding

Tear Drop Attack

RIP Defect

Fragment Flooding

The firewall also masks common ports that are frequently used to attack networks. These ports are made invisible to a would-be hacker. You can turn the firewall function off if needed; however, it is recommended that you have 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.

To view and configure Firewall settings, click on the Advanced tab in the Main menu and click Firewall in the Sub menu.

Figure 10-1: Firewall Configuration Main Page

Under the Submenu, click on Firewall Options to enable other critical Firewall options such as:

SYN Flood

ICMP Defect
