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?

80, 443 for HTTP/S, and 587 for a VPN service. Reason being that I travel frequently, and often have to connect through a bunch of different networks, Airport WiFi, mobile roaming, hotel WiFi, etc. and you never know the kinds of network restrictions they impose on their pipes.

80 and 443 is least likely to be dropped, while 587 is a common SMTP port that could make it through most networks.
