• How can I have a LAN party or similar event using Steam?

Any Steam game, when played on a LAN or otherwise, requires that each individual client be able to authenticate via the Internet.

At a LAN party, this means that Internet access must be available to every machine on which Steam games are being played.

If desireable, the network administrator of such an event can limit internet access to only the TCP/IP ports which Steam needs. These are:

UDP 1200
UDP 27000 to 27015 inclusive
TCP 27030 to 27039 inclusive

At large events, it will be necessary for each attendee to let their games fully update before attending to avoid taxing the shared internet connection with too much content delivery.
