enabling it to protect your network users. Select “Enable” and click the
“APPLY” button to open the Firewall submenus.

Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack,
UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

leaving it enabled to protect your network users.

disable Firewall module function” field, be sure to press the
