I've googled it and searched here too but no luck.
I want to host a multiplayer game in my local network but I can't because the game doesn't bind on IPv4 only on IPv6.
I disabled IPv6 in my internal network but still no luck. I don't need/want UPnP because even if it worked on my router I'm behind double NAT so the router first router will block the request and I anyways want to host a LAN-party i.e. there is no need server to be reachable from the outside world and to be advertised by the lobby server
I simply want to host a game and others in my local network to connect per IP to my box
Thank you in advance
Local network multiplayer game doesnt listen on IPv4
Re: Local network multiplayer game doesnt listen on IPv4
What OS are you running WZ on?
Run the game while specifying the command-line option:
--debug=net
Click on "Options" in the main menu, and then click the small "Open Configuration Directory" link in the bottom-left. Keep this window to the configuration directory open.
Then start hosting a game, wait about 10 seconds, then quit WZ.
And then find the latest log .txt in the <config dir>/logs folder, and attach it here or on a new GitHub issue.

Re: Local network multiplayer game doesnt listen on IPv4
Thanks for the help.
I've opened a bug https://github.com/Warzone2100/warzone2100/issues/2881
The game is installed from snap because the version in my distro is pretty old.
Looking at the log I see that the game itself closes the IPv4 socket
Can I somehow override this behavior? I don't see any option that can force IPv4 only
Debugged a bit more. Disabled again IPv6 on the host and the client
So from the client I see that the game is listening on the host
But the client says "error while joining"
And this is what I see in the client log
What Received error 5 is ?
Looks like the error might be on my end(what a surprise )
The hosts says
Client version is
Installed the snap version and it WORKED
thank you guys
