Strict NAT Driving me mad


Recommended Posts

Hi all.

I have a Netgear WGT624 V3 with my 360 connected to it. I got the Xbox just before christmas set up and It reported my NAT as open. (Used the same IP as my old Xbox was using do the ports were already forwarded) Fired up gears of war and Played CO-OP with me hosting. All worked no issues.

Haven't hosted a game until I tried yesterday. Gears told me that I could not do this as my firewall is too restrictive.

Run the live tests and it shows my NAT as Strict. No settings have been changed on the Netgear or the 360.

I have tried every thing I can think of. I deleted the port forwarding and set it up again. I can play online fine so I know the ports are setup correctly. I put the 360 on the DMZ, I even reset the Netgear and set everything up again from scratch.

NAT is still reported as strict.

I remember there was an uptate for the Xbox that was supposed to fix Network/NAT issues a few weeks ago, I suppose this could be the issue.

I am running version V4.2.11_1.0.1 of firmware, UPnP is on and I am out of ideas.

Has anyone got round this with any success? any have any ideas?

My NAT changes depending on the time of day, what day it is, etc.

Basically I have determined that my ISP gets flooded with users, and as a result that affects me directly.

I took the time to do all of the correct Port Forwarding, DMZ, all of that.

If also took the time to set up a Static IP as well, want to try setting up a Static IP, which made no difference for me, sometimes it was open, sometimes it was Moderate, which led me to my conclusion about it being my ISP, these are the best directions I found.

Look for the post by Silent Snipest which is the fourth one down.

Good Luck. I think for me it is Cablevision. It is rare now I do get moderate, but when I do, I blame them.

Sorry if I bumped this and I wasn't supposed to but it seems as if you haven't solved your problem. I used to have the same router and used firmware version 1.0.128. That was the last version that was XBL compatible.

The firmware that you say that you're using is only availible on the WGT624V1 and WGT624V2.

If I were you, I'd restore the factory defaults and change back your settings, 1 by 1, to find out what's wrong.

Have you tried connecting your modem directly to your console? This happens when you assign and address to the console and set that IP in the DMZ? You've tried rebooting everything after, right?

Sounds like an issue with your router.

I feel you pain man! Even with my xbox 360 in my router's DMZ I was still having problems. Then I found some security setting was enables (i think it might have been 802.11x related), after disabling it things worked fine. Not sure what your solution is, just wanting you to know that you may get things working if you keep at it.

Can you plug your internet connection directly into your xbox 360 w/o going through your router/switch?

Yep, I heard you friend. Tried every suggestion imaginable; Fowarded the right ports, put the 360 in the DMZ, UPnP is on, the router firewall is off, the modem firewall is off, tried giving the 360 a static ip, and all for nothing. If you ever make any progress make sure to give me a private message or something. Not sure about you, but I hate not being able to co-op/host anything on GoW.

If the DMZ is not working that leaves 2 options:

A - Your Router is Broken.

B - Your ISP is blocking the ports instead.

The DMZ puts you "outside" the firewall (NAT) and if that doesn't work what else can it be?

I know some ISP that block certain ports for certain customers who have used a lot of bandwidth certain ports, but I havn't heard of any issues with ISP blocking XBL ports.

If you do have DSL, hook your computer up to just the DSL modem, log into it and make sure all of the security settings are disabled, let your router handle that.
