I have pretty much the exact same issue. I have the same configuration as the first post (except IP address are 192.168.2.2 for client and 192.168.2.4 for server)
Now, this set up worked fine under Windows 2003. I could connect to the server from the steam browers LAN list, and players on the WAN could connect and rcon would work, all great. I've now moved to Debian (For those that don't know, pretty much the same as Ubuntu) and now I can see the server from the WAN and LAN, but I get the "unable to connect to rcon" error when I try the rcon command.
(I might be muddled up) but I know RCON uses TCP 27015 and the game uses UDP 27015. Whats the issue? This is really annoying.
The same problem is present for all HL2 games and is most certainly linux specific.
