Multiple Servers Same Machine

[jonnerz]

Is there anyway to host multiple servers on the same machine?

 

When attempting to host a second server on a different port, I get the following error:

 

Thu Jan 26 18:32:17 2017| Server UDP: Error receiving from 127.0.0.1, error: An existing connection was forcibly closed by the remote host, received bytes: 0
Thu Jan 26 18:32:17 2017| An exception occurred: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted

 

I have access to two IP addresses, and can use any other ports. So either can I bind the server to use a specific IP address (rather than localhost) or can I change change all the ports the server uses? It appears ports 27003, 27020 and 27021 remain un-changed when the game port is changed.

 

In-fact, if I turn listed and steam networking off the server only uses the game port. However, I still get the error above despite there being no port conflict.
