Configure Firewall
More than just a “NAT” firewall, there is a powerful Stateful Packet Inspection (SPI) firewall option that can be activated on the router. 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 the router’s SPI firewall.
The following steps explain the configuration of the router’s SPI firewall. As incorrect configuration to the firewall can result in undesirable network behavior, you are advised to carefully plan your firewall security rules.
1.Under the SECURITY CONFIGURATION command menu, click on Firewall
Configuration.
2.First, enable the firewall. You can choose among the Default Low, Default Medium or Default High security options for convenient setup.
3.Then you may choose the type of network activity information you wish to log for reference. Data activity arising from different types of protocol can be recorded.
The packet types that you have selected in the Accepted section will be displayed in the firewall log if they are detected by the firewall. This also applies to the Denied section.
