This page allows the Router to enforce specific predefined policies
intended to protect against certain common types of attacks.
Stateful Packet Inspection (SPI) is a packet inspection process
that blocks unwanted and unrequested packets trying to reach
PCs on your LAN. A DoS "denial-of-service" attack is
characterized by an explicit attempt by attackers to prevent
legitimate users of a service from using that service. Examples
include: attempts to "flood" a network, thereby preventing
legitimate network traffic, attempts to disrupt connections between
two machines, thereby preventing access to a service, attempts to
prevent a particular individual from accessing a service, or,
attempts to disrupt service to a specific system or person. Port
scan protection is designed to block attempts to discover
vulnerable ports or services that might be exploited in an attack
from the WAN.
When you have selected the desired Firewall settings by ticking
the corresponding check boxes for the various types of protection
offered on this window, click
