More than just a “NAT” firewall, there is a powerful Stateful Packet Inspection
(SPI) firewall option that can be activated on the access point. Stateful
inspection compares certain key parts of the packet to a database of trusted
information before allowing it through. Common hacker attacks like IP
Spoofing, Port Scanning, Ping of Death and SynFlood can be easily thwarted
with Compex’s SPI firewall.
To learn more about SPI firewall, read our whitepaper at
www.cpx.com or at
