Recently I finish my multiplayer script for a new game, so far it works great on the lan network. But when a client try's to connect over the wan netwerk, he just get's a black screen. On the forum it says that the router ports should be forwarded, so I did that but still a black screen appears for every client that try's to connect from somewhere else in the country. This is how the situation is; server to my router, than from my router to client his router and than to client.

For the server I use; -sv -cl -port 2332 -pl WL
The client uses; -cl -ip 87.208.9.255 -pl client

Can someone tell me what I'm doing wrong?

Might be firewall issue on either the server/router or clientside?

Thanks D3D, I will try that out, and let you know if it works or not.

I've checked the firewalls, and they should not give any problems. But still the client side gets a blackscreen. But know I also get a "error server not found" on the client side and than the blackscreen. Hope someone can tell me what I'm doing wrong.

Does anyone know how I can fix this?

Start a DOS shell on the computer running the server
then type:

ipconfig

The first IP tells you on what IP the server can be reached
within your network.
(when you run client and server in one closed network)


instead of an IP, try to use "localhost"
this often works too.

Thanks Damocles for your help. But my game works fine on my lan network, I only get a black screen on the client side when I try a game on the wan. Closed networks won't be any problems, but I want to play my game against some friends in other city's. So hopefully you or someone else know another solution?

This was a bug whose status I'm unaware of:

Set the client to the port that the server is on...

So if you do

-sv -port 2333

Then do

-cl -port 2333


This is NOT supposed to be the way; the client should find the port on its own. But we had similar problems and this fixed it and we reported it and I'm not sure what has been done (given that we reported it for A6 and now all work is on A7)

Hey fastlane69, thanks for your help, but I tryed it but still the client side give the error "server not found", and then gives a black screen. So hopefully you or someone else know another solution?

To narrow down your problem, try ruling out other variables:

Ok, you can first download the chatserver I made
http://www.wasteland.at/GSTNet_chatserver.zip
(runs on port 2300)

This server-program works, and with this you can test if your problem
is connected to your firewall/router.

If it works, you can rule out, that this is merely a simple "firewall" blocking,
or wrong router setting.
Then you know this is caused by a 3dgs problem.
