Bad Company 2, TCP keep alive

[Swenomorph]

Hello!

After 3 minutes of online play I get disconnected from "Battlefield: Bad Company 2" (PC). Reinstalling/updating/other fixes won't work. Every other game I play works and this problem is beacuse of EA's bad programming.

After reading this forum post by developer DICE I think I understand what causes these problems (EA forum). I get no keep alive from the EA servers and the connection is terminated.

I was wondering if I can somehow change the time before the ports close manually, or if there's any other method of fixing this since EA hasn't adressed this long existing problem?

PS. I'm not too good with networks so please explain so that a mere gamer understands
