Hi there i am having a lot of trouble getting port forwarding working on my new TP-Link ER707-M2 i have tried both Omada cloud and the standard web interface for port forwarding and neither are working i am trying to host a minecraft bedrock server and every time i try to port forward both the local IP for the computer and the Public IP for WAN it gives me this error "The external port has already been assigned to other rules." My other problem is to fix this i would assume i would need a second interface (It is only showing WAN in options for port forwarding) to show up to allow me to add that but i either don't know how to do that or it is simply not giving me the option to any advice would be highly appreciated
