Hey, sorry for the late respons. I had to wait for my neighbours to get access to their computer so I could test the client side with them. Anyway it still isn't working. I tested several options:
I disabled the firewalls on server and client side;
I opened several ports;
Also placed the server at my neighbours and made myself a client, so I could test their router.
Anyway the next link shows a image of my router configuration, the lowest line is what I use for my gameserver.

Hopefully someone can tell me what I'm doing wrong.
Thanks anyway,
Molotov.

Again: does any other Multiplayer program work? Try any of the many games, that can
create a connection between two computers.

You need find out if that is related to 3dgs or not..

1) You only have UDP enabled on that port. I'm not entirely sure, but I think that the initial connection requires some TCP traffic. Duplicate or simply add TCP to the connection and see if that works.

2) Does your router have a DMZ function? That will open your server to the net and usually let's 3DGS applications fly true.


3) Finally, do you even NEED to use a router? Can you connect directly to the net and avoid any 192.xxx addys? We had a similar problem: at home with a router we could not connect in. Disabled everything, did everything we could, blah, blah, blah. Nothing worked. Once we took the router out and connected directly: voila! Don't ask me WHY this worked, I was just happy it DID work!

Hey Damocles and fastlane69, I will try your suggestions and will let you know how it comes out.

Sorry for digging out this old thread, but if i remember right (haven't done multiplayer for a long time), opening the -port is not enough. Check out this side on direct play:

Try to also open port 6073 on the server. I will do tests on this very soon, because I'm working on a multiplayer project again.

Hope this helps some folks searching for the right router configuration.

I´ve the same problem. Theres a black screen (because he doesn´t find the Server) over WAN. I opened all ports and disabled my firewall but it sill not work. Over LAN I see it through a camera on the ground but i can´t control.
And molotov, can you send me your code where LAN goes and if it works now over WAN then please send me that code. Then I can try, too.
(WAN = Wide Area Network; for example: big company networks or the internet)

P.S. excuse me for my poor englisch, i´m german!

Hey GCMarc, I still haven't fixed my WAN problem. Also I recently started on a new multiplayer project where I tryed many possibility's to inprove online play. The multiplayer script I always use is based on the MultiPlayerBarebones by Locoweed. This can be found on the forum somewhere or on Locoweeds site. The camera on the ground is a basic multiplayer problem and can be fixed by starting your camera code on the clientside. Also you should take a look at the player_input function in the MultiPlayerBarebones, this is important if you want to move a character on online games. Last advice from me, try to put as many things on the clientside. For example, a tree on the server sends additional data to every client, but you can also use ent_createlocal to create a tree only on the clientside. In my new game I create every thing on the client except the player and other moving objects. Hope this helps, Molotov.

By the way, when I finally succeed in playing a game on WAN I will post the solution here.
