A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

How do you handle SSL certs and internet access in your setup? (lemmy.world)

tldr: I'd like to set up a reverse proxy with a domain and an SSL cert so my partner and I can access a few selfhosted services on the internet but I'm not sure what the best/safest way to do it is. Asking my partner to use tailsclae or wireguard is asking too much unfortunately. I was curious to know what you all recommend.

I have some services running on my LAN that I currently access via tailscale. Some of these services would see some benefit from being accessible on the internet (ex. Immich sharing via a link, switching over from Plex to Jellyfin without requiring my family to learn how to use a VPN, homeassistant voice stuff, etc.) but I'm kind of unsure what the best approach is. Hosting services on the internet has risk and I'd like to reduce that risk as much as possible.

  1. I know a reverse proxy would be beneficial here so I can put all the services on one box and access them via subdomains but where should I host that proxy? On my LAN using a dynamic DNS service? In the cloud? If in the cloud, should I avoid a plan where you share cpu resources with other users and get a dedicated box?

  2. Should I purchase a memorable domain or a domain with a random string of characters so no one could reasonably guess it? Does it matter?

  3. What's the best way to geo-restrict access? Fail2ban? Realistically, the only people that I might give access to live within a couple hundred miles of me.

  4. Any other tips or info you care to share would be greatly appreciated.

  5. Feel free to talk me out of it as well.

I came here to upvote the post that mentions haproxy, but I can't see it, so I'm resorting to writing one!

Haproxy is super fast, highly configurable, and if you don't have the config nailed down just right won't start so you know you've messed something up right away :-)

It will handle encryption too, so you don't need to bother changing the config on your internal server, just tweak your firewall rules to let whatever box you have haproxy running on (you have a DMZ, right?) see the server, and you are good to go.

Google and stackexchange are your friends for config snippets. And I find the actual documentation is good too.

Configure it with certificates from let's encrypt and you are off to the races.
