I know metarouter is kinda "retired", but as I have no other options for zerotier+MIPS other than through OpenWrt, I seek for an advice if what I want to achieve is doable at all using MT and I thus can avoid a need for extra server .
I have mAP-2nd with LTE modem attached via mini USB, and a set of "iot" devices connected via WiFi.
I want to make them accessible via my zerotier network to few servers on internet using MQTT
So I thought I can use Metarouter feature with stripped down custom built image of OpenWrt with zerotier and mosquito mqtt bridge modules, so I should be able to fit it into my mAP.
I don't want to reflash MT entirely.
Are there any obstacles that will prevent me from achieving what I am looking for from Mikrotik point of view (like some MT limitations of Metarouter implementation), assuming I get OpenWrt+zerotier+mosquitto up and running?
As an initial test, I have installed OpenWrt image on mAP and was able to interact with it via command line. I know I can make small enough image of latest OpenWrt with zerotier and mosquitto. But before jumping into all of that, I would like to ensure I am not missing any known limitation of Metarouter that will block me on later phase.
