I don't know how to do it through the launcher properties (I imagine there's a way though). The 1st time you use the link below it will ask you for the program to use it with. The 1st selection that shows up should be steam.
steam://connect/216.52.148.29:27016
There's a link to this called "Direct Connect" at the top of our forums, and the team speak channels all have this link available by highlighting any of the TS3 channels in the IL2COD sections - look to the right of the players - don't stare at the women too long though
