Sorry, I failed to point out my current network configuration.

I have 2 internal networks which use NAT, one class C ( )
and one rfc1918 ( ).

The internal interface(bge1) is configured with the class c network and
I have added a route to bge1 for All traffic on the network internally is routed via the gateway to get to
the network.

Hope that makes sense.
