For those who are playing BC2 in the same network as another person:

Many are experiencing getting kicked when a friend on LAN joins the same server. To fix this:

Steam
- Go to Steam's My games menu
- Right-click on the BFBC2 and select Properties
- From the General tab, click the Set launch options button
- Add a different client port number on each machine between 27005 and 27032 in the following format:
- Code: +clientport 270XX (Where XX is a different number for each system - do not use 27020)

DVD
- Right click your shortcut for BFBC2; change your Target to something like "../../bfbc2.exe" +clientport 27011

you seen this MF? and have you tried it?
