Omg its seems its working with cgnat, ill give this a try

I got 2 q+ tv boxes running armbian for h6

1st one runs as my dns server + sinkhole via technitium (pihole is a bit janky on them idk why) 2nd one runs as my unifi controller + samba fileserver + torrent downloader

Reason why i went with this is because they are cheaper than sbc or 2nd hand laptop

Fun part is that they are running at 20w/h in total
