Netgear Orbi RBK53 upnp map not showing on firmware 2.5.1.8
As the subject says, with firmware 2.5.1.8 I can't see the upnp table in "Advanced - Advanced Setup - upnp" in the website, the page stays blank.
the reason I'm trying to see what ports are setup is because I need to port forward UDP port 123 to an O2 Boostbox but every time I go to set it up I get a message saying the port is already in use with another device but I can't see what device (I have checked all the other pages mentioned in the attached picture).

UDP Port 123 is the port used by the Network Time Protocol (NTP). Orbi uses NTP to set its own clock. My guess is that forwarding UDP port 123 to a different host would interfere with the Orbi knowing what time it is. In fact, every device on the network that knows about "time" probably sends requests out port 123 and expects responses on port 123. If those get "forwarded" to only a single host, then nothing on the network will know what time it is.
Or.... I could be mistaken. I often am.
I have not created any UPnP maps (not even sure what that means). My page looks like this:
