My TCPIP skills are good, but not an expert, so there might be someone up
here with a more difinitive answer.

I believe the problem is that both sides of your server are on the same
subnet, 192.168.0.x.
You should set the two up on different subnets
ie
192.168.0.x for the external
192.168.16.x for internal
