Router Feature Descriptions

Since IPX sends several types of control packets that could keep

communication links permanently connected, control of updates and spoofing

techniques are employed to reduce this traffic. Specifically, RIP, SAP,

Watchdog, and serialization frames are filtered and spoofed. RIP and SAP

update frames are only sent piggybacked with data packets. SAP requests for

the nearest server are spoofed, serialization frames are dropped, and

Watchdog frames are spoofed.

IPX-RIP is similar to IP-RIP except IPX-RIP includes a time delay in

addition to a hop count.

Bridging And Routing Protocol Filtering

Filtering can be used to allow efficient usage of network resources and

provide security for your network and hosts.

IP Internet Firewall

The FlowPoint router supports IP Internet Firewall filtering to prevent

unauthorized access to your system and network resources from the Internet.

A security violation can occur when a packet is received from a WAN link,

typically connected from the Internet, which has the source IP address of a

host on your LAN. This filter discards packets received from the WAN

which have a source IP address recognized as a local LAN address.

Note: Most routers’ Firewall implementations protect against one form of

intrusion. The built-in protection Firewall of the FlowPoint router does not

take the place of a professional Firewall system designed to protect against

multiple violations.

Bridge Filtering

Bridge filtering allows a network administrator to control the flow of packets

across the router. Bridge filtering can be used to ‘deny’ or ‘allow’ the

transmission or reception of packets based on a ‘matched pattern’ using a
