Help please! Can't connect IP and others can't join.

Hi guys!

This problem drives me insane.

Didn't have problems before I moved and got a new PC.

Could allways open a coop game via Doomseeker or connect [IP].

But now it just doesn't work.

Forwarded ports of course!
(UDP 5029 and 10666).

"connecting..." just repeats in the console. Nothing happens.
Should join immediately.

WEIRD THING is:
I can join another friend online (but he has a very bad connection, so lag-galore on huge maps!)
but not others
and they can't join me!

I don't know anymore.


ANY OTHER GAME on Steam (etc) has no problems creating or joining a coop-game!!!


It's really annoying, especially when I tried to introduce some people into Doom who did never play it in coop.
But its things like these, that scare off potential newcomers!

If you can't join other people, then there is very little a Doom source port is supposed to be able to do automatically for you. This is likely a local firewall issue (on your PC or gateway) or you need to call up your ISP.

Any idea why only Doom has this problem?

10666 is a not a standard port number, and is only typically used by select Doom source ports. You have only tested Zandronum (as far as anyone could tell, because you never actually stated) so that "Doom source ports" is actually a vague answer, as there's a few other protocols and ports:
vanilla Doom over IPX tunnel, Chocolate Doom (2342 UDP), ZDoom (5029 UDP host, randomly allocated guest), Odamex (10666 UDP host, 10667 UDP client (configurable)) and Zdaemon (couldn't care enough to check).

using Zandronum and Doomseeker.

Like I said,
it's really weird, because we can only join ONE opened game,
but I can't be joined.
