Strict NAT - Xbox One - Cox - Motorola SBG6782-AC

I got my Xbox One day one and have always had some sort of NAT issue. At first I'd be moderate nearly all the time. My router died and my modem was quite old so I replaced them with a Motorola SBG6782-AC back in May. Since then, I've been in strict
NAT land more often than not. DMZ and UPnP did nothing. Port-forwarding the wired MAC SEEMED to help for a while, but I recently noticed that my NAT is strict again. It's not a huge deal in the short term as there isn't a ton to play online (aside from Titanfall
which sidesteps this issue).

Notes:

• I also have a 360 and getting online with that system is painful as well. I've done no port forwarding on my 360 as I'm more concerned about my Xbox.
  
• I have a PS4 and have only played that online a very small amount, but it doesn't seem to be a problem. The NAT on that system was showing up as a number that support equated to being open.
  
• I have a PC and don't really take that online for playing games ever, just purchases.
  

Ideally, I'd just like to be able to play this fall's games without sitting in NAT hell. I'm open to returning my modem selection for another as it seems that this piece of Motorola hardware may be a headache (I hear its UPnP integration is garbage).
One potential issue is the short list of preferred modems from Cox (see below). I'd like to eliminate the ISP as the headache as much as possible. This particular Surfboard is supposed to be Cox-supported, but even after working with their tech support line,
it doesn't seem to be handling Live very well.

Any help would be appreciated. If there are other Cox users out there, are there modem/router combos (hybrid or otherwise) that have worked well for you? Thanks in advance!

Strict NAT on Advanced Warfare

I'm having this problem with advanced warfare where it's says I have a strict NAT but my NAT on the dashboard says I have a moderate/open. My brother and I both have this issue. The modem we both have is the Motorola SBG6782-AC Cable modem. Hopefully I
can get some help. Thanks

 

Keep Receiving 'Error 8015190E' and 'Can't Connect to XBOX Live'

Have you tried to restore the Motorola Surfboard SBG6782-AC to factory defaults?

 

So...After digging around my set-up some more, my Xbox One lost its static IP on the console itself. I went ahead and changed the DHCP settings back to what it should be and it now works (for now).

I assume all will be well until it loses the static IP address again. I'm assuming either a monthly update or a hard boot may have wiped that information out. Very weird...

 

Dont ever use DMZ nd uPnP at the same time uPnP helps with ur ports, have you tried a static IP and port forward or port triggering? also is IPSec turned on normally found in the firewall section? another thing is on the xbox go to ur network altanate mac
and clear it, it will restart ur xbox one

 

I'm having similar issues but the difference is my 360, Wii U, ps3, and ps4 have no issues with NAT but my xbox one has given me plenty of headaches. I have cox and am using a Motorola modem and a trendnet router. My NAT used to be strict all the time,
finally got it to open but now it says I've got a cone NAT. My issues got worse during the Destiny Beta and now have issues even doing party chat with friends. They can hear me but I can't hear them. I've spent the past 2 weeks reading up and trying all
the different suggestions I found online similar to what you've tried yourself. At this point after 13 years having xbox as my main system I'm about to raise the white flag and give up. I've had no issues on PS4 and if that is the only place I can chat and
play with friends then that's where I'm going to have to go.

 

First thing: bring behind a cone NAT means everything is fine with your network.

Second thing: of you can join parties and your friends can hear you, it's normally not a network issue. If it was a network issue you would not be heard, too. So it's supposed to be a different problem. Maybe it's a problem with your headset or chat settings
in general. Also during the destiny beta it was a known issue, that chat was not working when docked and then got undocked during the game.

Suggestion is to do a cache reset (hold powerbutton for about 15 seconds), check all your chat settings, especially "sound on / off" and then try again.

If that doesn't help it's recommended to open up a new thread on your problem, so you may get better tailored help for it and it is not really related to this issue here.
