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.
