Firewall Protection
The Barricade Plus’ firewall can provide the 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.
Note:
When you select the “Enable” radio button of the “Enable or
disable Firewall module function” field, be sure press the
“APPLY” button.
