Example: You want packets with the TOS low latency bit to go 
through VC 2 (via gateway 127.0.0.3 – the Motorola Netopia® 
Gateway will use 127.0.0.x, where x is the WAN por t + 1) instead 
of your normal gateway.
You would set up the filter as shown here.

NOTE:
Default Forwarding Filter
If you create one or more filters that have a matching action of for ward, then action on a 
packet matching none of the filters is to block any traffic.
Therefore, if the behavior you want is to force the routing of a cer tain type of packet and pass 
all others through the normal routing mechanism, you must configure one filter to match the 
first type of packet and apply Force Routing. A subsequent filter is required to match and for-
ward all other packets.
Management IP traffic
If the Force Routing filter is applied to source IP addresses, it may inadver tently block commu-
nication with the router itself. You can avoid this by preceding the Force Routing filter with a fil-
ter that matches the destination IP address of the Gateway itself.
