How do I get rid of a port-symmetric NAT?

For the last week my gaming consoles have been stuck behind that NAT and I have been unable to resolve the issue. I tried routing my XB1 through my router's DMZ, but the NAT still comes up strict. I've forwarded all the necessary ports and the NAT is still strict. I contacted Microsoft support and they were unable to help me and just a little while ago, I contacted ASUS support and they were no help at all. I even bought a new Linksys EA 6400 router (which I really liked) and had the same issue. I wound up returning it and went back to my ASUS RT-N66U.

The thing is though last week I was having issues with my internet, which were resolved on Thursday. Up until that day, my NAT was open on both consoles, but since then they've been strict. I can connect to the internet with my various devices and it runs smoothly, but when I try to play a multi-player game on my Xbox, the lag becomes unbearable.

I am at a loss and do not know what else to do. I've never, ever had this issue before nor have I ever had trouble forwarding ports on my router.

Someone help me, please.

Try calling your ISP, and ask them to assign you a public IP. Unfixable NAT issues could be stemming from the fact that they're routing you through a private IP.
