Since the search key does not appear to work properly, here's how you connect to the server when you are the lobby leader..

First, Make sure you can access the developer console, normally the ` key, but check in your options.

Then when you are the lobby leader execute the following commands in the console before you hit 'search for server'.

1) sv_cheats 1
2) ms_force_dedicated_server 85.234.148.2:27105

That's it, once those 2 commands have been run it forces everyone in the lobby to connect to that address.

Enjoy, and let me know how you get on.
