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
