Firewall
The Wireless Barricade 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 enabling it to protect your
network users.
Access Control
Using this option allows you to specify different privileges based
on IP address for the client PCs.
