Hello, i want to play lfs with my friends but i can't.
I create a server directly from game but when they try to come in it says "ClientConnection:connection failed".

I tried with dedicated server but same error.

What to do to fix that?
Thanks.

allow the port u choose in ur firewall.

You mean Firewall > Advanced >select network Settings then there to add or in router settings port forward? If no can you explain me how to allow the port?

Thanks.

No that is it exactly. Why don't just try? It doesn't hurt or something.

I was try, i do all like lfs manual but again same error. Before 1 year we played normal, just create server then join. But now.... i dont know what is happening.

Anyone?

Go intro your router, add this:
Tcp 29339 and 63392
Upd 29339 and 63392,
I have network from tele2 so i add like this, you need to find place with games where you can open your ports.

Quote from GeneraL.W :

Anyone?

It's either your router which isn't correctly configured with NAT port forwarding or your firewall blocking LFS communication ports.

63392 of joordy is just an example, you might have another port configured, we don't know.

If you still can't figure it out we need at least a screenshot of your router NAT port forward settings, screenshot of LFS hosting screen and you need to make sure you have your Windows firewall turned off.

Thanks to all i fixed with restart router and again port forwarding.

Thanks.
