Even though I have exams coming up, I still manage to squeeze in the odd round or ten of Team Fortress 2. I blame Valve for releasing the medic achievements recently.

(7 to go! One of them is ‘Family Practice’, so I need some more Steam friends to deploy an ubercharge on, hint hint. Also, for all the spies out there: FYI I am a medic – please call for me sometime eh?)

Anyway, I had been playing for a while, but had developed a problem connecting to servers. The problem was that most of the time I would get into the game, take a few steps, then it would freeze. A second later I would get the red “Connection to server lost. Disconnect in 29…28… seconds”. Sometimes I would only get to “retrieving server info” or “sending client data”, and sometimes I could play for as long as 30 or more seconds before I got ghostbusted (yes, netrek jargon). I’m sure I even got a kill after being disconnected.

Trying to rejoin would give me a “This Steam ID is in use on the server”, while my friends saw many “BertieB(1) has connected”. And I saw a lot of “Disconnected from server. Reason:” … connection to server lost… this steam ID is already in use…

This is not unique problem. Fortunately the fix is fairly straightforward.

You need to open some ports on your router:

TCP 27030 – 27039
UDP 1200
UDP 27000 – 27015

For people with a BeBox (a Speedtouh 780 WL I think, so it should work for similar Speedtouches, like those with BT internet) you can simply log into the router (at, go to Toolbox -> Game & Application Sharing -> Assign a game or application to a local network device -> Half-life 2. Easy!

This may not solve the problem for everyone, but it did for me and others. Good luck!

Update: Thanks to Jeroen, who pointed out the typo that has been there for about 3 years.
