Sorry, I failed to point out my current network configuration. I have 2 internal networks which use NAT, one class C ( 188.8.131.52/24 ) and one rfc1918 ( 192.168.1.0/24 ).
The internal interface(bge1) is configured with the class c network and I have added a route to bge1 for 192.168.1.0/24. All traffic on the 184.108.40.206/24 network internally is routed via the gateway to get to the 192.168.1.0 network. Hope that makes sense.
