Asus rt-ac86u UPnP question

[Silentsoul]

I recently purchased a new Asus rt-ac86u to replace my older rt-ac68u. With the old router As long as I had UPnP on I would have Open NAT on PC1 and a moderate NAT on the PC2 in COD ww2. With the new router which has the identical firmware version as the old one I can't get either Pc to be open without port forwarding and then the 2nd pc becomes strict NAT. Any ideas? Is there a way to check if UPnP is actually working?

FW: 3.0.0.4.384_20308

Is it possible to get an open NAT on both pc's?

the issues is a port conflict in stock firmware that asus never fixed, merlin fixed this issue in his firmware. I wish they would fix it.
