[PC] Game disconnected. Port 3659

[MalcolmBlk]

"Game disconnected: Client closed down connection. Check your network connection and make sure that port 3659 (UDP) is open." This problem is not just with few servers, it a problem with every server I am trying to connect to. Checked the network, it was fine. I'm sure that bf4 is not blocked or anything. Bf3 is still working. Bf4 compain is still working, of course. I know, there are some questions like mine allready, but others don't specify if that problem ocures with every server or just with one.

For Battlefield on PC, please enable the following online ports on your connection:

TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300

For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

For some reason, it wouldn't let me log in as an admin. I mean, the webpage where you need to open these ports (I'm using D-Link). And if you're logged in as a user, it doesn't let you open any ports. Anyway, I don't get this one: why do I need to open that port, if I didn't close it? Bf4 was running fine for like a year. Could it just randomly close the port? Tried the EA method, still isn't working. Do I need to open all the ports you mentioned, or just the 3659 UDP one? Actually, bf3 is working, doesn't that mean port 3659 is open? I thought, bf3 and bf4 are using same ports.

Ok, what ip address I need to tipe in when opening these ports?
