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.

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.

Tailscale is very popular among people I know who have similar problems. Supposedly it's pretty transparent and easy to use.

If you want to do it yourself, setting up dyndns and a wireguard node on your network (with the wireguard udp port forwarded to it) is probably the easiest path. The official wireguard vpn app is pretty good at least for android and mac, and for a linux client you can just set up the wireguard thing directly. There are pretty good tutorials for this iirc.

Some dns name pointing to your home IP might in theory be an indication to potential hackers that there's something there, but just having an alive IP on the internet will already get you malicious scans. Wireguard doesn't respond unless the incoming packet is properly signed so it doesn't show up in a regular scan.

Geo-restriction might just give a false sense of security. Fail2ban is probably overkill for a single udp port. Better to invest in having automatic security upgrades on and making your internal network more zero trust
