So, here’s what I set up:
Docker with some containers behind Gluetun
Gluetun gives access to the local network so I can access the containers on my home network through http.
The only port I exposed to the internet is the 32400 for Plex.
I reach my home network remotely only through Wireguard, my fritzbox router has a guided setupt that gives me a wg configuration so I just scanned the QR code with my phone. I learned this opens the default wg port.
Now, you can never be 100% safe, but is my simple setup safe/solid enough?
9 times out of 10 I thinker with it when I am at home
It’s still a work in progress and I am open to any kind of suggestions
I’m doing basically what you’re doing, with the main difference being that I have a VPS that tunnels external traffic through a handful of exposed services. I do this so I can get TLS working properly (they all use LetsEncrypt certs, and auto renew).
Yours is simpler, and if it works, great! I would echo what others said here, don’t expose Plex unless you actually want to access Plex remotely. Once something is exposed, it’s going to get hit with all kinds of automated spam.
