There's no support for it. You can, technically, run a server if you want to emulate with QEmu or ExaGear, however, performance will be severely limited. Whilst running from your Raspberry Pi can help with server costs, unfortunately, for a public server, it is not a great idea, as it will use your network connection. A common DDOS attack will render your server (and your own internet) offline with absolute ease, and network connections for a residence aren't supposed to be used for running a public game-server, though running something for friends (private) is almost always permissible.

Raspberry Pi's are great for home servers but that's about it.
