Reverse Proxy vs VPN: How do you access your home-server?

The more I am selfhosting the more ports I do open to my reverse proxy.

I also have a VPN (wireguard) but there are also 3 family members that want to access some services.

Open ports are much easier to handle for them.

How many users do you have and how many ports are open?

My case: 4 users (family)/ 8 reversed proxy ports

How many users and open ports have you?

You're comparing apples and oranges, reverse proxy and VPN serve two different purposes.
- Though in this context they're both being used to provide safe access to local hardware from the internet.
  
  They probably want the pros vs cons of this specific situation
May I ask what do you guys have exposed to the internet?

I personally just have a wireguard VPN (single UDP port open) and everything is accessible through an internal reverse proxy. I just never felt the need to expose nothing ant least not web related.
- One thing I need to publicly expose is my own instance of Mealie. It's a recipe manager that supports multiple users. I share it with family and friends, but also with more distant acquaintances. I don't want to have to provide and manage access to my network for each and every one of them.
  
  What made you pick Mealie over other stuff like Nextcloud Cookbook or Grocy or whatnot?
- I have Jellyfin and Jellyseerr open through cloudflare -> nginx over port 443 so i can share it with friends. Eventually I'll do the same with NextCloud probably.
  
  Video streaming is against Cloudflare policies, aren't you worried that they'll may block your account?
- Just Navidrome for music streaming.
- That’s exactly how I have my setup, and on my client WireGuard configs I have it set to split route so I can connect to my home VPN without disrupting anything else.
- I expose self-hosted bitwarden for my family to access through cloudflared tunnels and only allowing US IP via cloudlfare rules. Only the webUI is exposed and traffic has to go through cloudflare and nginx to be able to do anything.
- a lot of stuff:
  
  owncloud
  
  paperless
  
  immich
  
  jellyfin
  
  jellyseerr
  
  traefik
  
  than i have stuff only accessible from local, like the *arr stack.
  
  i'm not using cloudflare or anything, should I?
  
  the only exposed ports i have are http / https and a random port for ssh.
  
  i also don't use any sso... maybe i should set one up.
- KitchenOwl, and a Matrix server and Element web interface.
Both. Some things are only resolvable internally or over wireguard. Some things are publicly accessible via a reverse proxy.

Overseerr, bitwarden, plex all have ports open or through the reverse proxy. Same with email and a few other services. All the *arrs are accessible only on my network or over VPN.
- this is the way.
  
  also fail2ban to ensure that nobody bruteforce it's way in.
- Curious why you keep the arrs internal only, when there are things like Authelia that could secure access to them?
  
  Because no one needs access externally. Overseerr is public facing and passes the requests to the arrs.
  
  It's not about secure access, it's that no one outside my house, me included, really needs access to them at all.
VPN because I don't know enough about all the random arrr services to expose them trustworthily.
Tailscale with reverse proxy, nothing publicly exposed
- Do you even need a reverse proxy if you're using Tailscale? What advantage does it give you over setting up your DHCP correctly such that you can access your services by hostname?
  
  Because I have my own custom domain internally and don't use tailscale while on I'm on my network physically. But I get the best of both worlds, however I do have Tailscale setup with DNsMasq to set to my domain name anyway instead of using the Tailscale domain
Reverse proxy and allowing connection only to IPs from my country.
- Out of curiosity, how do you accomplish that?
  
  I know cloudflare has a free tier and allows you to put rules like this in place. AFAIK you'd have to use them as DNS at least in order to use this feature. I use Cloudflare tunnels and access to facilitate remote access to my home-server, and I know I have this same rule in place.
  
  Cloudflare DNS basically, but it can be implemented at nginx level using geoip2 modules (I do both, because some of my services don't play well with Cloudflare proxied DNS). The cumbersome part is keeping geoip database up to date but I'm sure there are plenty of tutorials online.
  
  I’m using an nginx reverse proxy with maxminddb for geo filtering. I have it limited to my state instead of country. If I could reliably go more specific I would. I really only rely on external access to the reverse proxy for family. I could use a vpn myself but I’m not bothering with the inevitable and endless questions from family.
  
  I don’t know if it’s realistic or not but I would love to use a client certificate to authenticate with the reverse proxy but I’m not sure of the compatibility with mobile devices or smart TVs. If it would work even a self signed cert that’s valid for years would be a nice layer.
I've got a reverse proxy for stuff I want to be able to hit from the outside. It's behind an SSO portal with 2fa (hardware token). Then for everything else I VPN in.
- What are you using for SSO?
  
  I'm not OP but Keycloak is pretty usable for SSO. I've configured about 8 different web apps to be integrated with it via OAuth2.
  
  Not op, but I'd recommend looking in to keycloak.
Probably the usual. 80/443, wireguard, a couple game servers.

For those of you who staunchly put your open ports on a VPS and wireguard tunnel it back to your home server, are you firewalling that wg connection to only allow specific traffic?
- I used to, but less so now, I get that weakens the separation.
  
  Mostly the vps is hardened to f and that's my defense but I agree it's a bad one.
Wireguard, as only a handful of people need access to the services, I manage it manually - and not with Tailscale or something similar.

With that my server looks nothing like a server from the outside, as I'm exposing nothing - Wireguard doesn't even show up in a port scan
- I like this approach, but I'm currently sitting in a foreign hotel who's wifi seems to block WG. Annoying. Keep a TLS-protected reverse proxy for things you might need through obscure networks.
A reverse proxy isn't a substitute for a VPN for access outside your network. And it isn't any less secure; you only need to open 1 port however all of your services will be accessible via that single port which is arguably less secure.
- Everything that is managed by that RP, yes. One should obviously be careful when selecting what to expose.
Currently I expose port 22 for SSH, 443 for Nginx and a couple extra for Syncthing (to mirror my media files between a Hetzner Storage Box and my NAS at home).
There's a specific setup I tried to build once but didn't manage:

Expose only Wireguard port from my VPS

make it so that when (and only when) a device is connected to the VPS via Wireguard, then mydomain.xyz will target the VPS' IP (and therefore hit my Nginx proxy which redirects to my various services at myservices.mydomain.xyz.

I tried by having a Adguard Home running on that same VPS, and setting its IP as the DNS in the wg0.conf that goes on the client device but it didn't work.

Caddy Reverse Proxy with Basic Auth for services which are critical like my 3d printer. Without auth for other services like my website or jellyfin and such. I use docker for everything so that's another layer of safety for me.

I have port 443 open and use subdomains for most stuff. Some other ports for non-HTTP services but I don't have any right now.
Depending on the services you provide, the usual standard ports. So if you run http/https services, port 80 and 443 respectively.

You seem to answer your own question.
Anything that is exposed is done through nginx proxy manager and 2FA is enforced on those apps either through the app or through Authelia.

Some of the exposed apps are shared with friends and family so easier to expose securely than mess with VPN for them.

Anything else is only accessible via VPN on my router.

I need to look at tailscale.
I use a self-hosted vpn, because I don't want to expose anything to the internet. The ones I do want to, I haven't set up yet since it would require reinstalling my pi. But I do have a reverse proxy set up on a vps that I will use once I get around to doing it.
Never open ports to the internet unless you want everybody to see it. Always use VPN to access your selfhosted stuff. If you've got a lot of VPN connections to set up, try generating a QR code for the connection. Makes it a bit faster to setup the client.
I use Wireguard for everything except a couple of ports that are open directly to Internet for Traccar (fleet management) because the GPS trackers don't support anything in the middle and I use Cloudflare Zero trust tunnel for Nextcloud (without any other security layer because the Android and Windows app don't support them) because my family use it too. The Wireguard tunnel is always on both on my PCs and on my Android smartphone.
I have two nginx ingress running on my cluster. One of private one public. Public one is what's exposed on 80 and 443 to the net.

The private is only available via VPN or lan. The public is for services I want internet exposed.

My family have a VPN network set up to my lan on their router and have access to most services but the public stuff is for the internet friends
I never open any ports to the open Internet other than the two my friend client uses.

For remote access I use a P2P VPN called ZeroTier leaving it always running on the Pi, and switching it on for the remote device when needed. It's free for up to like 50 users and is very powerful, but dead simple.
- free for 25 users
Isn't the point of a reverse proxy to only have to open the port to the reverse proxy and nothing else?
