Playing COD MW3 & Running out of NAT sessions....
Edited by Wyze on Nov 13, 2011 at 4:28:07 AM

Playing COD MW3 & Running out of NAT sessions....

 

I have the AT&T U-verse Max Turbo Internet package with download speeds up to 24 Mbps. It has been working well for the past couple of years as my son and I use it simultaneously to play most of the latest and greatest online multiplayer games together... World of Warctaft, RIFT, etc... This has worked very well even when we have guests over and they connect using this same connection. We can have three or four people playing online without any issues... Recently we assembled two brand new machines as a hobby project with most of the latest and greatest hardware. Could this be why when we are playing the new Call of Duty Modern Warfare 3 we have this problem.... "Running out of NAT Sessions"? I say we play but we really don't because before the first game is over we are both lagging so hard we really can't play. I have called AT&T support a dozen different times but they have you reboot the equipment with only temporary results. Once they sent out a technician who completely replaced their equipment but within a day it was back the same way so laggy we can't play. Finaly after a dozen logged complaints to AT&T about this issue one rep had the insight to tell me to look at the NAT Sessions table and sure enough it was completely locked up...But he could not tell me how to fix it... I have been searching the internet for any solutions to this situation and the closest I have been able to find was a guy posting about his Skype program causing the exact same issue "Running out of NAT Sessions" and his resolution was to limit the upload to about 1/2 of what he was using in the skype program. I have not seen anywhere in the Valve / Steam client that I can do this (that is what is used to play MW3 online) Is anybody else having this issue? Does anybody out there know enough about networking, routers, LANs, and NAT Sessions to give me another clue as to how to resolve this because AT&T isn't going to do it for me... SAD FACE 8(


 

Images To Show The Difference:




Good Connection Not Really Doing Anything Here...







Try To Play Call Of Duty MW3 w/ My Son And Then We Get This NAT Session Overload...







We can get in a game or maybe only a half of a game before the internet connection goes to complete garbage... And thanks to that one guy who said check your NAT Sessions table I am now aware that I have a NAT Sessions table and it does appear to be full... Any thoughts? We can do the whole reboot the Modem / Router show etc... and then get in part of another game but I know this should not be like this... Our internet connectivity was excellent for almost two years and now all of the sudden... Fun Time Is Over!

I do not know about any of that other than to say I now know it has absolutely nothing to do with COD / MW3... I did start poking around in the AT&T 2WIRE MODEM/ROUTER Gateway and found a Firewall Setting under Attack Detection at the very bottom that was not checked... I just checked it and rebooted the AT&T gateway..

Do you have uTorrent or similar running on either of these machines?  Worse still, on both?

 

If so, try lowering the Max Connections to some reasonable value.

No. This issue occurs while running one program, the same program, COD MW3, on two very fast computers... Nothing else is running except the game... I boot up and start playing by myself and I can play for hours but the second my son connects and attempts to play or vice versa... the images above show what happens... I do not know enough about networking / NAT Sessions to know how to fix this issue... I did not even know what a NAT session was until last week... But it appears from what I have read on other posts across the internet about other programs etc... that the modem / router is not letting the "check packets" back in or something and they are backing up and one guy fixed this by limiting his upload and then his Skype started working. Which this was not AT&T equipment or even the same program we are having issues with...

This is pretty straightforward - something on your son's machine is consuming IP sessions.  That is what NAT is all about - read http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080094831.shtml

 

 

I still cast my vote for a torrent downloader or similar.  If you post a large section of the NAT table (at least a few hundred lines), a bright person may be able to tell what is consuming the sessions.

It is not just my son's machine and it is not any other program. I think you are missing the details of information in that it does not matter which of us logs into the game first (and nothing but the game) when another person logs in the AT&T router / modem becomes overwhelmed with these "NAT Sessions" incoming that it almost stops working altogether the internet connection speed drops down so something unusable as show in the images. Thank you for the link I will go read that now. But to eliminate any confusion you may have there is no torrent program or anything else running on any other machine. It is only two machines running the Call of Duty / Modern Warfare games online multi-player... I have been playing for hours (by myself) this morning. I am now level 42 but if my sons logs in the internet will crash and then neither of us can play. This also works in reverse. My son can play for hours without interruption. However, the moment I log in and try to play with him the same thing. We get overwhelmed with these open incoming "NAT Sessions" that neither of us can then play. So it is now one at a time or nothing until we solve this little mystery. Thanks for the link going to read it now.

Thank you for the link it was very educational. After reading through the link you posted it almost looks like the AT&T router / modem has insufficient amounts of DRAM (Dynamic Random Access Memory)... Maybe if they would increase the amount of DRAM this issue would go away? Are we forced to use the AT&T equipment or can I go out and purchase a superior modem / router with enough DRAM to play the game on multiple machines and still use the AT&T U-verse ISP connection?

Although you can not use another Modem, you can use your own router between the Uverse supplied Modem/Router and the rest of the network for your computers.

I have considered dropping AT&T altogether over this issue and purchasing a T1 connection but from what I have read a T1 connection would not be as good as the AT&T connection even though it costs considerably more... Unless we purchased a bundled T1 so that we had two T1 connections and then that would be fine for just me and my son as long as we did not have any company trying to connect but we can not afford to spend $600.00 a month on an internet connection. So unless we drop all AT&T services and share a T1 connection (I don't think this would be enough to play MW3) , we are then stuck with the AT&T U-verse... The only other thing I can think of would be based on your link and that hints that we may need a better Modem / Router than the AT&T supplied equipment so we can have more DRAM...

$50 or $60 will get you a decent wireless router which should clear up your connection issues as well as probably improving your wireless network as well.

 

Are you joining online servers?

Are they dedicated servers?

If your not joining dedicated servers, you are actually running P2P (multiple connections to multiple computers).

Have you tried games with a lower limit on the number of players?

Does the same thing happen if your playing something other than MW3?

We have two wireless routers: The one AT&T provided and the Cisco router I used before AT&T. However, we do not use the wireless aspect of the router. We only connect with network cables. I am going to try the suggestion offered and connect my Cisco router to the AT&T router and then connect both computers into the Cisco router and see if that helps anything...

My Cisco router is unable to connect to the internet via my AT&T router for some reason... I do not know enough about networking to determine why I am unable to access the internet through two routers connected to eachother. I find it strange that I would have to. One router has always proven to be sufficient in the past no matter what ISP we used... While I consider the purchase of yet another router does anybody else have any suggestions as to how we can resolve this issue aside from purchasing a third router?

No need for a third router.

 

This is what I did to use an "internal" router (when I had Uverse). I set my "internal" router to use DHCP or Dynamic for the WAN address, plugged it's WAN port in to a LAN port on the 2WIRE, reboot the "internal" router, let the 2WIRE assign a local address to the "internal" router and then set that address to the DMZ in the 2WIRE's management interface. When I go to the "internal" router's management interface it shows as having the same WAN, gateway, and DNS addresses that the 2WIRE uses.


I set the "internal" router to assign addresses to "my" side of the network in a different IP range than what the 2WIRE uses (192.168.2.* instead of 192.168.1.*) but using the same subnet mask (255.255.255.0). My internet works fine with no interuptions and local network tasks (back ups, streaming, etc.) work as expected. I can also still access the 2WIRE from "my" side of the network when I need to without having to change any network settings or swap any cables. Leave DHCP running on the 2WIRE. You do not need to disable the firewall in the 2WIRE as the DMZ will open a pinhole through it to the address you pick (your internal router). If you have existing wireless on your router that your satisfied with and want to keep, just make sure to turn off the wireless in the RG.


As for any STBs, they should be run straight out of the RG with CAT5 or RG6 Coax.


If you currently have your router behind a basic DSL or Cable modem, Your setup will be pretty much the same. The 2WIRE will replace your modem, then go into your existing router and change it's internet connection type to Dynamic or DHCP. Then change it's internal network IP adress and DHCP Pool and you should be good to go.

Just went to Fry's and purchased a brand new router and have paid the extra fee to have them come out and install it for me this week. The sales people on the floor were all pretty much in agreement that you simply disable the AT&T router and only use the 2WIRE modem (because you have to) and then use your own router and the problem will be eliminated. This sounded a lot like what you have provided here as a solution although I do not completely understand everything you said it kind of sounds about the same. So the issue should be resolved this week. Fingers crossed! Thanks for all the help!

This sounded a lot like what you have provided here as a solution although I do not completely understand everything you said it kind of sounds about the same. So the issue should be resolved this week. Fingers crossed! Thanks for all the help!

This issue is not limited to games either.


Today I was simply working remotely when I suddenly found myself unable to open Notepad on a machine. The machine was completely frozen / locked up. So I switched over to another machine and checked the NAT Session table and tada! The exact same problem without any video games involved. In case you are unable to read the screenshot it says...


Current NAT Sessions

session table 0/1024 available, 919/512 used in inbound sessions:

FWIW: 512 concurrent sessions seems like a gracious plenty for normal home use.  I'm wondering if COD:MW3 has a P2P software distribution server/client that is eating your ports alive.

 

And also, FWIW, I can't imagine any reason in the world why a lack of available NAT sessions in your Internet router would cause Notepad to lock up on a PC, unless there is software also running in the background on that PC that reacts poorly to not being able to setup network connections.

I do not know about any of that other than to say I now know it has absolutely nothing to do with COD / MW3... I did start poking around in the AT&T 2WIRE MODEM/ROUTER Gateway and found a Firewall Setting under Attack Detection at the very bottom that was not checked... I just checked it and rebooted the AT&T gateway..

And now I am up and working with quality connection speed... My son will be home any minute and we will test COD/MW3... I hate to get excited at this point but I am starting to suspect that I may have found the problem and resolved it myself... So then the questions become "Has that been checked for the past two years?" & if so then "How did it become un-checked?"

With several macines running and COD / MW3 being played by my son and I at the same time we appear to have the internet connectivity that we have come to expect from AT&T over the past couple of years. It is really looking like I found the issue. One little checkbox... Now how in the world do you suppose that became unchecked in the first place? Why didn't any of the tech support tell me to look there? Well in any case I suppose I should simply be happy that it appears resolved... Now about this new router I just purchased... Do I keep it and use it or simply use the AT&T gateway device? I suppose that would be a completely new thread...
