What does the console NAT Type say? Have you tried putting the console in the DMZ or setting NAT to open instead of secure?

I fixed this by calling my ISP and getting myself off their "CGNAT" (effectively causing a double-NAT scenario) UPnP or any port forwarding was not working at all until I got that rectified
