Hi all, I'm trying to setup my Fritz Box 3390 with port forwarding for my PS4. Whilst I have UPnP enabled I would still like to open the correct ports to ensure an open NAT - I'm already using exposed host (DMZ) for my Xbox One. Here is an example for the PS4 opening port 443: Port Forwarding enabled for: Other Applications Name: PS4 TCP 443 Protocol: TCP From Port: 443 through port 443 Computer: PS4 IP Address: 192.168.0.13 To Port: 80 It's the last bit "To Port" I'm confused about. It always defaults to 80 but shouldn't I changed it to 443 for the example above? If so what would I enter in the To Port part for a range of ports e.g. 10070-10080? Thanks for looking in.
