Hello,

I set up a Mythruna server but when I try to connect I get an error message and the error log shows this:

Code:

I have a linux machine on which I'm virtualizing a Windows Server 2012 R2. The linux box has an external IP address, the Windows server doesn't. I use iptables nat rules to connect the ports I need on the windows machine to the internet.

Are there any other ports than 4234 TCP required to succesfully join to the server?

Greetings

Sorry you are having trouble.  You need to forward both UDP and TCP... same port.

Edit: oh, and I think the three consecutive TCP ports also.  So 4234, 4235, 4236, 4237 on TCP but only 4234 on UDP.
