Firewall
52
Advanced Setup Method
The VoIP Router's firewall enables access control of client PCs,
blocks common hacker attacks, including IP Spoofing, Land Attack,
Ping of Death, IP with zero length, Smurf Attack, UDP port loopback,
Snork Attack, TCP null scan, and TCP SYN flooding. The firewall does
not significantly affect system performance and we advise leaving it
enabled to protect your network.
You can select a pre-defined firewall level from the drop down list.
Available options are High, Medium, Low Level & User Defined.
Select User Defined to manually adjust the firewall settings.
Note: After you check the radio button in the "Enable or disable

to display the list of firewall features.
