I've had to find a solution similar to what you are looking for. My need was due to being double NAT'ed where I had no control over the internet facing router/NAT.

Personally, my solution was to use Oracle Clouds free tier service to host and NGINX reverse proxy as Oracle also offers free static IPs to there compute instances. From there I used Tailscale to join the instance to a Proxmox container running Docker on my server running services I wanted exposed to the internet (Emby, and a few 'Arrr apps). I've found it to be remarkably stable (much more than I expected).

An alternative method is to use Cloudflare tunnels, which are very easy to get setup. It in essence is the same principle as above but using Cloudflare's 'reverse proxy as a service' type product. I was not able to use this for my needs as Cloudflare do not allow media streaming.

If you do choose the first option, I would recommend isolating the server running the exposed services to its own network that cannot touch your day-to-day network. I also recommend configuring ACLs in Tailscale to restrict traffic to specific ports from specific hosts to minimise any risk of having exposed services. Oh, and automatic updates to the OS and services is ideal.

I saw you are using basic HTTP auth, whilst it is secure enough it does have some issues with making connections more difficult, particularly if you are using any of your services API's (it is also not the best user experience IMO). I would recommend setting up oAuth/SSO if yunohost supports it.

Lastly, as other users have said, even if you don't use either suggestion, put a reverse proxy on it. NGINX Proxy Manager is a nice friendly solution with a web GUI if you are not too familiar with proxy configs

If you are cool with using Cloudflare, you can use Argo Tunnel to expose HTTP(S) services to the internet with DDOS protection and all of Cloudflares features.

They've made it free some time ago, you just need a pc/server in your network running the cloudflare agent software.

I've hidden everything behind Wireguard.
externally my server doesn't even have open ports. everyone who uses my services gets a Wireguard key.

don't know how many people you wanna service or if it's just you - then Wireguard could be a viable solution

I'd disagree with the other post (Running any software on your home network is insecure, but so is having your network connected to the internet).

You should not be opening ports in general. There are various ways to do this:

1. Create a site-to-site wireguard VPN with a lightweight VPS from someone like Digital Ocean, install a reverse proxy + WAF on this VPS, and setup a tunnel between it and your network.
2. Use a service like Cloudflare Tunnels (free) to basically do the same thing

Generally, your host should be on it's own network/vlan with limited/no access to other VLANs within your network.

Google cloudflared tunnels, zeroteir and tailscale. They all solve this exact problem, I've been using cloudflared tunnels to host without exposing my ip for while now, it's relatively easy for https services.

Edit: also just because services require login, doesn't necessarily make them secure if their implementation is terrible. It's best practise to use a reverse proxy like nginx which specialises in having not shit security for authentication, and proxy your services behind it.

It's best practise to use a reverse proxy like nginx ... for authentication

What kind of authentication are you using for nginx? Just basic http authentication with a .htpasswd file?

That's what I'm using right now, but I've found that not all services play nice with it.

Running a federated service on your home network is just a bad idea in general. You're screaming to the world "hey look, there's a server running potentially exploitable software here!" Even if you hide the IP behind a VPN.

For everything else not so public as a federated service, best bet is to install a WireGuard VPN server on your network. Set it to some random high number port. Undetectable, basically. Then when you're away from home just connect to the VPN and it's basically just like you're still hooked to your WiFi at home.
