I'm setting up Multicraft on a server. Everything works fine, but if you try to start a server on a dedicated IP, we get this error:
2013-10-03 13:57:40,458 INFO server 16: [Server] INFO Starting Minecraft server on x.x.x.x:25565
2013-10-03 13:57:40,463 INFO server 16: [Server] WARNING **** FAILED TO BIND TO PORT!
2013-10-03 13:57:40,464 INFO server 16: [Server] WARNING The exception was: java.net.BindException: Cannot assign requested address
2013-10-03 13:57:40,464 INFO server 16: [Server] WARNING Perhaps a server is already running on that port?
We're using CSF, but I disabled it and the problem still occurs. In CSF I have a range of ports starting from port 25565 in both TCP_IN and TCP_OUT.
