Are you exposing any ports on your home server? (lemmy.world)

Maybe I'm using the wrong terms, but what I'm wondering is if people are running services at home that they've made accessible from the internet. I.e. not open to the public, only so that they can use their own services from anywhere.

I'm paranoid a f when it comes to our home server, and even as a fairly experienced Linux user and programmer I don't trust myself when it comes to computer security. However, it would be very convenient if my wife and I could access our self-hosted services when away from home. Or perhaps even make an album public and share a link with a few friends (e.g. Nextcloud, but I haven't set that up yet).

Currently all our services run in docker containers, with separate user accounts, but I wouldn't trust that to be 100% safe. Is there some kind of idiot proof way to expose one of the services to the internet without risking the integrity of the whole server in case it somehow gets compromised?

How are the rest of you reasoning about security? Renting a VPS for anything exposed? Using some kind of VPN to connect your phones to home network? Would you trust something like Nextcloud over HTTPS to never get hacked?

I don't technically open any ports to the public. I have a site-to-site wireguard tunnel to a hosted server. The hosted server is running a hypervisor with two virtual switches. One switch is my external switch and only my Wireguard server is using it. The other is an internal switch where I place other VMs for separate things. A container host, a terminal server with xrdp, a monitoring server with netdata, stuff like that. All technically, but unnecessarily, accessed through nginx proxy manager.

Because it's site2site with my home equipment on the Wireguard server, i can still connect to my home network where i host a number of separate services like HomeAssistant from outside the home network.

I don't use tailscale, but Wireguard vanilla is super easy to work with. I also have fail2ban pretty much everywhere I can install it because it takes up practically zero resources.
