Firewall

The BLW-04EM firewall can provide 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.

Access Control

Figure51

Using this option allows you to specify different privileges based on IP
address for the client PCs.
