Additional Network Ports for Multiplayer Gaming: With an Open Nat does it mean the ports have already been port forwarded?
To whom it may concern,

I recently gotten an upgrade on ISP and I had to port forward my PS4 to get phenomenal connections, my Xbox One was already pretty good without port forwarding and I seemed to get an Open Nat and good connections without using the method. However I wanted
to try to port forward the Xbox One on my Comcast router but it kept giving me an error message and try again later. Is it because the ports are already open that it won't allow me to do the forwarding or is there another issue.

I know if the PS4 is doing good with this method the Xbox One will be beyond great.

have you tried checking to ensure both Xbox are on Open NAT? Also check individual ports for those particular games as some games require additional ports to play without issues. Hope this helps
