My first try at self hosting, and I have some questions... (lemmy.dbzer0.com)

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

If you use WireGuard for local access, I don’t think you need to open any port on your firewall, unless you are sharing your plex with other people that do not have access via WireGuard. But I know just enough to get me in trouble, so I’m sure I’ll be corrected on this.

No, you are correct. If you are the only person accessing the service you don't need to open any ports since you access your network via Wireguard anyway.

90% sure wireguard (the VPN server) is going to need an open port if you want to connect from the outside.

This is correct. But the port wont reply to anything but a valid client, so it should not be too apparent to a would-be attacker that you have a port open at all.
