Battlefield 3 problem connecting to same server on LAN

Question

In Battlefield 3, I'm able to connect to a server with a first computer, but the second computer in the LAN will always keep on the "connecting..." phase. I think that happens because I was using the same port.

Origin uses registry to launch the game so I changed the registry to use another port:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\GameUX\Games{438D1154-48C0-41FD-BDB0-BC789AAA5BE3}\AppExePath

using

C:\Program Files (x86)\Origin Games\Battlefield 3\bf3.exe +clientport 20000

But it didn't work. Also tried to enable/disable UPnP.

Of course both computers have different accounts.

Answer

had the same problem with a friend, we solved following the howto on this link on youtube and also opening the following ports on our router:

• TCP: 80, 443, 9988, 42127
• UDP: 3074, 3659, 6000, 25200

maybe it's helpful for you too (this doesn't work for everybody)
