I'm just setting up ArmA as a new game which we support (I run a GSP), and loking through the wiki, there is no mention of running multiple servers on one machine, or should I say specifying the IP address which each server is using.
As is normal with most games, there is either a command line varible to specify the IP or a variable in the config file, yet I can find no reference to either.
I have 1 NIC with 5 IPs attached to it which I use to run game servers on...This then allows each server to use the default port.
Anyone have any ideas?
