There is a misunderstanding on “port”.
The feature is (was) in /interface wireless, and is called “defaut-forwarding”, see:

https://wiki.mikrotik.com/wiki/Manual:Interface/Wireless#General_interface_properties
default-forwarding (yes | no; Default: yes) This is the value of forwarding for clients that do not match any entry in the access-list
(nothing to do with port forwarding)
No idea if it was moved in some later RoS or if the Hap AC2 OP has is using the “old” wireless or the “new” Wifi (or whatever).
@Chris
Please post the exact RoS version you are running and which wireless/wifi are you using.
