First off, I take it your network runs on the IP scheme 192.168.0.X right? If not, then the TWGS server is being assigned an IP address in which your router (and computers on your network) cannot see. And if you can't see it, then people coming in from the outside cannot see it either. 192.168.0.X is a loop back IP scheme, meaning it is not accessible from the internet unless the router properly forwards requests to it. So you need to go into the D-Link router setup and make sure to forward TWGS port requests to the TWGS server's IP address. It could be that when people are trying to connect to your server, they are hitting the router like they should but the router does not know where they want to go from there. You need to tell the router any requests on the port the TWGS server uses are to be directed to the TWGS server. I'm not sure what port the TWGS server runs on, because I've never set it up before. But if someone else here knows, then nothing should stand in your way of setting it up in the router setup page. See ya!
