Since the router we are testing is a standalone box, we are not using any routing protocols.
The actual testbed is using Gated. Here is the info from the router. Thanks in advance.

Could you please inform us about details regarding this problem?
Which routing software are you using? natd? routed? Interface
Characteristics (output of ifconfig of the interfaces)?
netstat -r
