Configuring Client Services

The Barricade includes a broad range of client services, including
firewall protection, network address translation, virtual server,
connection support for special applications, and restricted Internet
access for specified clients. You can configure these functions
using the Setup Wizard by clicking "Enter" at the bottom of the
Advanced Settings screen, or by selecting specific items from the
menu on the left of the screen.

Firewall Protection

The Barricade's firewall can 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.
