enabling it to protect your network users. Select “Enable” and click the

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.

disable Firewall module function” field, be sure press the
“APPLY” button.
