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.

5). Hey OP, don't worry, this can seem kind of scary at first, but it is not that difficult. I've skimmed some of the other comments and there are plenty of good tips here.

2). Yes, you will want your own domain and there is no fear of other people "knowing it" if you have everything set up correctly.

1b). Any cheap VPS will do and you don't need to worry about it being virtualized rather than dedicated. What you really care about is bandwidth speed and limits because a reverse proxy is typically very light on resources. You would be surprised how little CPU/memory it needs.

1a). I use a cheap VPS from RackNerd. Once you have access to your VPS, just install your proxy directly into the OS or in Docker. Whichever is easier. The most important thing for choosing a reverse proxy is automatic TLS/Let's Encrypt. I saw a comment from you about certbot... don't bother with all that nonsense. Either Traefik, Caddy, or Nginx Proxy Manager (not vanilla Nginx) will do all this for you--I personally use Traefik unless for some reason I can't. Way less headaches. The second most important thing to decide is how your VPS in the cloud will connect back to your home securely... I personally use Tailscale for that and it works perfectly fine.

3). Honestly, I think Fail2Ban and geo restrictions are overdoing it. Fail2ban has never gotten me any lift because any sort of modern brute force attack will come from a botnet that has 1000s of unique IPs... never triggering Fail2ban because no repeat offenders. Just ensure your VPS has a firewall enabled and you know what ports you are exposing from Docker and you should be good. If your services don't natively support authentication, look into something like Authelia or Authentik. Rather than Fail2Ban and/or geo restrictions, I would be more inclined to suggest a WAF like Caddy WAF before I reached for geo restrictions. Again, assuming your concern is security, a WAF would do way more for you than IP restrictions which are easily circumvented.

4). Have fun!
