(Solved) Disconnected constantly from BF3 if roommate joins same or different server

post #1 of 19
Thread Starter 
Hi, OCN! I have a rather annoying problem that I can't seem to find any information on in my web surfing. Whenever my roommate joins my server in BF3, or any other server, I run about a 75% chance of being disconnected. Now, when you're at about 17,000 points, you're going to be upset and hurl some obscenities out there; well at least I do. tongue.gif
I have tried searching the forums associated with the battlelog, and elsewhere on the net, and I can't find anything that pertains to this. I opened up the following ports, in the hopes that it might resolve the problem, but sadly it has not.

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

Any help will be much appreciated. Thanks in advance!]

EDIT: My problem is solved thanks to some of the fine members of our forums here at OCN. Thanks everyone! thumb.gif

Do you know of any way to resolve this problem, or have you ever dealt with it before? I'll google external ip conflict and see what I come up with. Thanks.

Since you're behind a router, you have the same external IP address as your roommate and anyone else connected through the router. My guess is that BF3/Origin checks IP addresses to ensure that no more than one account is signed on from an IP address. If this check is being done server-side there would not be much that you could do.

I thought it might be something along those lines. I figured that BF3/origin was flagging us as the same person or something along those lines and was disconnecting us because we were "duplicates". Just seems pretty stupid considering people play this game together in close proximity all the time, and this issue should have been foreseen. There has to be someone else out there in BF3 land that has this problem, so I'm suprised that there has been little discussion of it anywhere on the net.
I appreciate the input from all of you, +rep, and thanks.

I had this problem in bc2, though it hasn't happened to me in bf3. I found if I re-connected after the first kick I could normally get on with out kicking the people I played with. We'd get 4 people all hooked up at our house for mini-lans with bc2. If you connect does it kick your room mate?

i don't have to forward the ports and my wife and i can play on the same server at the same time...

nix your port forwarding, it's probably the cause... let the router hand the NAT on it's own...

Sometimes it does disconnect him after I reconnect, after I am dropped. Other times, it does not. It's very confusing to say the least.

Well, we had the same issues without any of the ports forwarded, so I don't think that would actually be the problem. The only reason I had seen any alleviation to the disconnects is because my roommate became obsessed with SWTOR, lol. I'll try disabling it anyways, and play around to see if I can get it to work without the port forward. Thanks! +rep

My Step father and I ran into that issue with BC2 and now BF3, generally only happens the first time one of us logs onto a server the other is on, then it goes away for the rest of the night. Re-joining is fine, and jumping servers all evening is also fine. It's a EA problem that has existed for a while, and they are not likely to fix it.

It's annoying, but I guess I'll just have to live with it. Sometimes We will disconnect each other again, if we switch servers again, but not always. Just a stupid problem, but oh well; the game is so good that it pretty much negates its problems.
