Intrusion Detection
•
Intrusion Detection Feature
Stateful Packet Inspection (SPI) and Anti-DoS firewall protection
(Default: Enabled) — The Intrusion Detection Feature of the
ADSL Router
limits access for incoming traffic at the WAN port. When the SPI feature
is turned on, all incoming packets will be blocked except for those types
marked in the Stateful Packet Inspection section.
RIP Defect (Default: Disabled) — If an RIP request packet is not
acknowledged to by the router, 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 from accumulating.
Discard Ping to WAN (Default: Disabled) — Prevent a ping on the
ADSL
Router
’s WAN port from being routed to the network.
