Has anyone had any luck configuring their TOT billion router (specifcally the Bipac 5200G) to forward traffic to an internal port? I'm tearing my hair out in frustration here as nothing seems to work.

I have had no luck setting the required NAT entry. I have also tried disabling the router firewall. The server is accessible on the internal network and my router can be seen by it's IP address internally, but not externally...

So I figure either the router isn't forwarding or I'm missing some important config step, but I can't be sure.

I have successfully setup the port forwarding on a Billion router without any problem.

Remember to test the port forwarding from outside the network. If you try to connect from inside the network, but connecting using the external IP it won't work.
