Multiple Xbox One Consoles, One Router, Open and Moderate NAT

Any luck with getting 2 xbox ones open on a router without having a second ip from isp?

Yeah, that would be great.

Thanks for all the feedback guys. But to be honest, this is a brutally difficult problem to trace.

For example, each time I start up both consoles, it's a different setup. Most of the time it's moderate/moderate. Sometimes it's open/moderate. Sometimes open/strict. Because of that, trying to track down a set of "working" criteria is nearly impossible.

I did try disabling static IPs. This ended up in strict/open. But is that because of DHCP? Or just because that happened to be the luck of the draw?

I disabled my web server on HTTP (80), so now I'm just forwarding HTTPS (443). No change overall. Weirdly enough, we can matchmake... sometimes. Occasionally the strict xbox will not see party invites. So it's not the end of the world but it is rather inconvenient
and I do believe results in the network errors we are seeing where connections are punted back to lobby (e.g., in Destiny).

I've emailed Asus and they were no help whatsoever, unable to shed light on the UPnP or IDGP nuances of their devices.

It seems a bit unusual to me that static IPs would be interfering with this. Every single device on my network is either on a static IP or is far enough away from the default starting DHCP range that conflicts will not occur. Are you saying that assigning
a static IP to the console somehow interferes with UPnP?

As for port triggering, I disabled all of that a while ago. It had no effect one way or another. With port forwarding, I do need some ports forwarded for other services, but I have confirmed that none of them are overlapping with the ports listed in my original
post.

Think that's still a potential source of the issue? I've emailed Asus with respect to the N66U and its ability to handle IDGP and UPnP.

Sri, WhiskeyGamer1, but portforwarding can always only be setup for one IP at all. You can not setup portforwardings for more than one adress. This is not working with the NAT protocol. Or better said, its impossible. Same with portriggering. The triggered
ports usually are forwarded to the IP which has triggered them, they cannot be forwarded to different IPs simultaneously.

Thats why you have to use UPnP.
