ICMP Filtering
Separate filtering support is provided for specific kinds of received ICMP packets.
Internet Control Message Protocol (ICMP) is used in IP networks as an internal protocol for nodes to exchange
control and diagnostic information. Applications normally will not use ICMP for any purpose.
Select the tab labelled ICMP Filtering to setup filters for received ICMP packets. Two tabs let you choose the
kind of ICMP packet to filter for each of the IP ports (LAN and WAN). Check the ICMP packet type to filter the
packet received on a port. Use the tabs on the left to choose the port to perform the filtering action on. Select
OK once all your choices have been made.
IPX Filtering
The IPX packets that are received by the RouteFinder can be selectively filtered or forwarded based on their
IPX address.
Default Action
A received IPX packet whose IPX source address or IPX destination address is not found in the filtering
database will be either filtered or forwarded as set in this field.
The default setting of this option is forward.
