Firewall
The firewall does not significantly affect system performance,
so we advise enabling it to protect your network users. To enable
the Stateful Packet Inspection (SPI) firewall, click on [Advanced]
under the [Firewall] section and select [Enable] and click the
[Apply] button.
The Barricade™ SPI 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.
