Hopefully this is the right place to ask this, if not could the tyrannical MOD overlords benevolent powers that be move it and not send me to the gulag a friendly PM pointing out the error of my ways please .

Okay, onto my problem. I have a D-Link 2750u router supplied by my ISP. Recently I replaced my XBox 360 with a shiney new XBone. My NAT has always been Open, with no problems. My new console tells me my NAT is Open in the Network settings. However, I recently bought CoD:AW (don't judge me please !) and for some bizarre reason the following happen:

- My NAT swings between Moderate and Strict on the in game screen, without any intervention on my part.
- Seeing as myself and other members from my country prefer to play local games (our digital bullets going missing mid Atlantic gets tiresome very quickly), we're having immense problems trying to party up in the game lobby (this is a NAT setting issue if memory serves). None of us have an open NAT in game anymore. I should also point out the XBone only got launched here last month, so it's a learning experience for all of us.

Now, this could be a game specific problem, but seeing as Activision is so green conscious (they recycle their only game after all and just give it a new lick of paint) and the cesspit that is the official forum has nothing about this problem that I can see, I'm thinking it might be on my side.

I've gone ahead and did some reading up on the subject. And this is where I'm not getting/finding the answers I need. Apparently I need to open/forward port 3076 on my router for the XBone (all other ports have been opened already as default on my router according to the Gaming settings, however this one is apparently a new one to forward or something) , and found that no problem on my routers setup. But being technologically handicapped, I have no idea what the other stuff means and what to select.

- Traffic Type: TCP, UDP or both?
- Application Name: FTP, HTTP, SMPT etc come on this list. What does Live use?

Also, how can one get a list of the open ports?

Any help would be appreciated, just use small words please .

The last time I got a NAT error regarding a CoD game I had to put my devices mac ID in the router so that traffic was unhindered.

Then again, it was a p.o.s. linksys router, so I might be completely off.

One of these two links might be useful:

http://portforward.com/english/routers/port_forwarding/Dlink/DSL-2750U/Call_of_Duty_-_Advanced_Warfare_-_Xbox_One.htm

https://community.callofduty.com/thread/200833047

The first link doesn't mention the port 3076, the second one specifies TCP and UDP as traffic type for that port though.

If your router mentions a DMZ (de-militarised zone), put your PC in that.
Are you using Wifi, or is it wired in? Wired is easier to manage, but your router might not care.

You listed the model of the kit you have, so I'll try to have a look later on.

Thanks. Had a look, gave it a try but now for my next battery of questions ...

My console has an IP address assigned to it from my router, right? But according to those articles, it seems I have to assign one manually to my device. So what address can I use? Whatever takes my fancy or the address I'm assuming my console has already? What about the Subnet Mask? Gateway and DNS would be my routers?

I connect only via WiFi. There is a section regarding DMZ in my routers setup, but says it's not a good idea to do so? Thanks by the way.

Nope. Can't find anything. Work-blocked :(

DMZs are useful if you want to open a PC up to the internet. It drops most restrictions, and means you've lost some of the protection the router provides. Stuff like games should love this, as there's less forwarding, blocking, etc, to get past.
Make sure your Antivirus and firewall are up-to-date and you're set.

IP addresses are assigned by your router's DHCP pool. It has a list of available addresses, and any device connecting through the router will be given an address off that list.
But, the list if usually only a fraction of the available addresses on the network the router runs.
Basically, if the IP of the router is 192.168.34.1, and the subnet mask is 255.255.255.0, the entire range of addresses 192.168.34.2 to 192.168.34.254. If the DHCP range is from 192.168.34.20 to 192.168.34.100, you can happily give something an address from .101. to 254 without much chance of a problem. Most routers use 192.168.x.y, with 'x' being the network number, and 'y' being the devices on that network. It's all down to the subnet mask. If that isn't 255.255.255.0, it gets messy, with more or less addresses available on that network.

Yes, Default Gateway is the router, and usually so is the DNS server. It's a good idea to look around the internet for an alternative DNS server to put in as a backup address, as the router will default to using the DNS of your ISP.

Well, problem solved thanks to you gents!
