I seriously don’t think they would fix this. No mention of this problem and the answer HQ actually suggests people to open their ports up! Had no problems with this game until Second Assault patch.
I went here,
wiretuts.com/battlefield-4-problems-and-how-to-solve-them/
Went down to the “punkbuster” clicked this

downloaded it, choose Battlefield 4 and where it was placed, the i run the install/update, never had a problem running BF4 ever again 
fixes the 3659 (UDP) port problem
I suffered from this issue… the only way to solve it is to open UDP in your router
You have to go to router settings
in other words your router will keep disconnecting you because port 3659 is not allowed in your router
to know how to do that. go to google search and put: how to open UDP in (Your router model)
Have tried that didnt work
After opening the port disable windows fire wall
Its working after i did that thing i said didnt need to do anything with the port.
Should not even have to fiddle with ports in 2014 for multiplayer games.
I fixed my problem. I forwarded my ports to xxx.xxx.1.2 and I had my ip manually set to xxx.xxx.1.4 for some reason (I don’t know). I switched my ip back to 1.2 and was able to join games now. But that still doesn’t explain why Smart Port Forwarding used to work when I needed it around the beta and launch, but wouldn’t work when I needed it this time around.
I’ve tried forwarding all the BF4 ports, repairing BF4, relogging into every account related to BF4, restarting the modem and router, turning off all firewalls, updating Punkbuster, updating Direct X, updating GPU drivers and I STILL can’t connect to any game without the 3659 port error. And it’s certainly not my router considering it worked perfectly up until they released SA. I’ve also gotten kicked out of servers with that error AFTER playing in that server for hours.
So I figured out that I can only join a game when it is in the pre-game lobby or the post-game lobby.
Dumped again…lost XP…Grrrr.
Ladys,
I have 260+ hours on this game. Out of these 260+ hours i have not once had a connection issue with this port. Now I install SA and have about 10+ hours on this and now have this issue.
So can someone tell me why its only now i have to start playing around with Ports?
It’d be really nice if DICE would ever acknowledge issues so I can actually feel like they’re going to fix an issue instead of hoping daily for something to be fixed.
Still stuffed!
moving to other servers does not apear to save XP either

Same problem, guess they took my money and ran AGAIN, theres only so long they can treat the people that pay their wages like this…
EA fuk up everything
One test you can try is turn off all firewalls except the one on your router that connects to the internet . That proves it is not a config issue with your PC. Also upnp on your router can cause issues so try turning that off as well. Check with your ISP that this is not being filtered out their end as well.
Got the “Client closed down connection” issue 7 times before finally getting a proper round in… and its an epic round… Its sad that such an awesome game is plagued by so many issues… BF 4 life.
