I've been getting a bad connection on my Xbox One and have been advised to try forwarding on my Hub 3.0
Ports I'm trying are 53,80,88,500,3074,3544,3659,4500 on both UDP and TCP
On the port forwarding page I'm putting 53 on each of the options (Local start port, Local end port, External start port, External end port) and when I click to add the rule I get the same error message for all of them:
The configured port range cannot contain one of the following reserved ports.
It does look like port 53 is part of our reserved list so you won't need to add this manually. If you set up port forwarding for the other port numbers does this help with your connection on the Xbox One?
In regards to port 53, you can check this link for more information if you wish > Port 53.
