Upnp on host router causes double nat.

[COD WARFARE]

Upnp on host router causes double nat on the R3, turning it off fixes it, but then this causes another issue of the other router devices certains one need to be on that router, no longer speaking to each other.

Chrome cast and google devices.

Any ideas on how to fix it?

That's tricky, you could port forward the ports they specifically need instead and then port forward all the other ports to the R3 and then they won't be conflicting but you should still get an Open NAT.

I fixed it !

Turned Upnp off on the R3.

Turned it back on on the Host Router.

Restarted both.

My R3 Wan address had changed oddly, so redid the DMZ and then just to make sure Port forwarded the R3 in the Host router for MWIII.

All Open again.

Thanks for getting back to me @Netduma Admin

what work for me is go to port forward and click dmz and put ps5 or xbox or pc in the dmz

yeah I had done that on its own, but it didn't work.
