Firewall
The Barricade’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.
Note: When you check a radio button in the “Enable or disable Firewall
module function” field, be sure to click the “APPLY” button.
