I just bought new Archer AX73 and it seems that port forwarding doesn't work. When I open ie. port 9000 in port forwarding and use https://www.yougetsignal.com/tools/open-ports/ to test it, it always says that port is closed.
I have NAS with openmediavault behind reverse proxy so I need to port forward ports 80 and 443. On old Archer C7 it worked well.
