How to connect to the Tnetserver.exe from anywhere around the world?

[speedyw03]

When I run TNetServer.exe on my computer, I can connect to the "server" by TNManager.Connect(X);
the x is the internal IP adress.
Everything works!
So I sent over a build to a friend and he can't connect..
I'm a little bit confused here, the tnetserver shows 3 IP adresses, only the internal works (only for me)

Internal address is (obviously) for internal use only. Outside people need to use your external address, and either UPnP must be functional, or you must open up ports on your router.

When I use external IP I get: Could not make a connection because the target machine actively refused it. btw my computer is swedish so I used google translate to translate the debug message.

I logged into my router and UPnP was enabled

That checkbox is grayed out, so it's unclear if it's actually functional or not.

Running TNServer.exe will tell you if the gateway is accessible or not. You won't see a gateway IP if it's not.

I've tried to connect to all three ports (5127, 5128 & 5129) and using the external address, but I still can't connect

When I posted the screenshot of UPnP I wasn't logged in as admin, now that I've checked it enabled

Not all routers allow you to connect using an external address. Your gateway is functional and ports get opened fine, which means people will be able to connect to you from the outside.

This is why TNet uses both by default. It will try to connect to an external address first, and when that fails -- to an internal one. That's how the server discovery works (it sends both).
