Agreed. I had loads of connection problems.. Could maybe log into 1 of 15-20 servers i tried. I then opened each port “manually” (DMZ did not work with BF4) TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127 UDP: 3659, 14000-14016, 22990-23006, 25200-25300 After I did this, I haven’t had a failed login once. All successful atempts! ---

funny thing is, you can still connect to an empty server and ‘not’ get that error. Try it.. seriously, why would I be able to connect to an empty server with no errors, but then suddenly get the Check your network connection port 3659 (UDP) on a busy server. ---

For port forwarding use the website guys [http://portforward.com/english/routers/port\_forwarding/](http://portforward.com/english/routers/port_forwarding/) [[portforward.com](http://portforward.com)] Choose modem/router , and modem/router model (if no exact one there, choose similar ones to your modem router) Choose Battlefield 4 get your local pc ip with CMD command " ipconfig " ( like 192.168.1.42 ) And do the instructions there for opening all necessary ports. (do not use program there to open ports, its a bit fishy program) ---

also make your PC a static IP, so all of that port forwarding will continue to work if your ip changes, if you can’t do that use localhost or 127.0.0.1 which should port forward those ports for everyone on the network.. ---

Ok this is a SERVER SIDE problem guys, when you get this error, server is kicking players or server crashes (server become empty), happened 2 times today on metro. And ports already opened… Error Game disconnected: Client closed down connection. Check your network connection and make sure that port 3659 (UDP) is open. ---

Or come up with a solution that works for households with more than 1PC and Origin-account. Portforwarding to one single pc is not a solution that will suffice in the long run.
