Honestly, i don't think anyone knows what is happening what is going on inside the docker-compose files i set my instance up with 0.17.4/prod file with some tweaks.
Gotta stick with the 1st rule of engineering: "If it works, do not touch it"
Also i don't know if my full works, cause i can federate with everybody except lemmy.ml (which i guess is a error on their end?)
Yea, its sometimes annoying when you have to manage 2 firewalls (still to this day i find the Oracle interface too messy), but it makes it secure
