uPNP rules not showing

I’m using a HAP AC2 as a home router with a cable modem.

I’ve enabled uPNP in IP → UPnP Settings, and ticked ‘Allow To Disable External Interface’ and ‘Show Dummy Rule.’
I’ve added ether1 (WAN cable modem) as External, and all other ports and wireless LANs as internal.

However I don’t see any uPNP rules appearing in the various firewall pages. I’m running Skype which usually requests these ports.

Any ideas?

I have exactly the same problem.
Using RouterOS 6.44.3

The uPnP port mapping command is accepted by the router without any errors, yet it fails to show in the firewall rules and doesn’t work.
The “enable dummy rule” is ticked but the dummy rule doesn’t show up either.

I strongly suspect this is a problem RouterOS.
