Just like the other commentor said, there are also another container management sowftare called komodo that you can also make it to notify you of new updates

I host my public game server "ports" over a vps, you can just simply rent a cheap/fast vps that is close to your home and configure wireguard to expose the game server ports, Amp cubecode will launch a similar thing to expose on a vps, if you dont mind paying i really recommend that

What model do you mostly use for those tasks

How does it work on the background, do i need to always have a termux session on?

Its not that difficult, i have mine set up with gluetun and I've been using for more than 1 year now, sometimes i have some problem with the search terms and every engine gets broken but i just need to search with another name

Some years ago i posted something simillar to your post, in conclusion it is safe to run on a vm and have the ethernet ports pointed to it, i personally use bare metal since im still not too familiar with opnsense to start thinking of migrating to a vm

I tried using docker on portainer for that on a different port but it didnt load, i will try to spin up a vm yo try it again

I just tried to test it and i dont know why but i cant access the qbit client, do i need to use a i2p browser for that?

Interesting, can you also share some public trackers that i could test with
