The table below lists the Intrusion Detection parameters and their

descriptions.

Parameter Defaults Description
Intrusion Detection
Feature
SPI and Anti-DoS
firewall protection No The Intrusion Detection feature of the Barricade
limits the access of incoming traffic at the WAN
port. When the Stateful Packet Inspection (SPI)
feature is turned on, all incoming packets are
blocked except those types marked with a check in
the SPI section at the top of the screen.
RIP Defect Disabled If the router does not reply to an IPX RIP request
packet, it will stay in the input queue and not be
released. Accumulated packets could cause the
input queue to fill, causing severe problems for all
protocols. Enabling this feature prevents the
packets accumulating.
Discard Ping to
WAN Don’t
discard Prevents a ping on the router’s WAN port from
being routed to the network.
