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've played around with reverse proxies and ssl certs and the easiest method I've found so far was docker. Just haven't put anything in production yet. If you don't know how to use docker, learn, it's so worth it.

Here is the tutorial I used and the note I left for myself. You'll need a domain to play around with. Once you figure out how to get NGINX and certbot set up, replacing the helloworld container with a different one is relatively straight forward.

DO NOT FORGET, you must give certbot read write permissions in the docker-compose.yml file which isn't shown in this tutorial
-----EXAMPLE, NOT PRODUCTION CODE----

    nginx:
        container_name: nginx
        restart: unless-stopped
        image: nginx
        depends_on:
            - helloworld
        ports:
            - 80:80
            - 443:443
        volumes:
            - ./nginx/nginx.conf:/etc/nginx/nginx.conf
            - ./certbot/conf:/etc/letsencrypt:ro
            - ./certbot/www:/var/www/certbot:ro

    certbot:
      image: certbot/certbot
      container_name: certbot
      volumes: 
        - ./certbot/conf:/etc/letsencrypt:rw
        - ./certbot/www:/var/www/certbot:rw
      command: certonly --webroot -w /var/www/certbot --keep-until-expiring --email *email* -d *domain1* -d *domain2* --agree-tos
