Firewall
The 802.11g 54Mbps Router firewall can provide access control of
connected client PCs, block 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, so we advise leaving it enabled to protect your
network users. (Firewall must be enabled in order to access
additional settings.)
Note: You must click the Apply button, located in the lower
right-hand corner of the screen, for your changes to take
affect.
Access Control
Using this option allows you to specify different privileges based on
IP address for the client PCs. To Enable Filtering Function, click Yes.
Note: Any PCs configured with Firewall rules need to be
added in the Access Control Table.
