hap ac2 lite, POE port - WAN Interface

Hi all, apologies if this is a basic question. I have a hap ac2 lite router which I want to use on a customer site which currently uses a Ubiquiti Aircube router connecting to a Nanostation AC Loco CPE which then receives internet from our network.

The aircube has POE out on its WAN port so it can power the Nanostation and send and receive internet traffic from the same port.

The hAP AC2 lite is using Port 1 for WAN and Port 5 for POE.

My question is, what is the best way to power the Nanostation from the POE port of the hAP AC2 but also use this port as the WAN port?

Thanks in advanced

On Mikrotik devices the text on the port labels is just that - the function is not fixed, unlike many Ubiquiti devices.

You have to swap the references of ether1 and ether5 throught the configuration, for the standard configuration this includes
Bridge port membership (ether5 becomes ether1)
WAN interface list membership (ether1 becomes ether5)
DHCP client interface (ether1 becomes ether5)
