Looking for a reverse proxy to put any service behind a login for external access. (self.selfhosted)

I host a few docker containers and use nginx proxy manager to access them externally since I like to have access away from home. Most of them have some sort of login system but there are a few examples where there isn't so I currently don't publicly expose them. I would ideally like to be able to use totp for this as well.

With that, I use Pomerium for apps which accept a HTTP Headers, for example, my Fresh Tomato firmware flashed router, it has a HTTP dialog. This allows me to login from the road if I need to manage something like rebooting it or updating firewall rules etc.

My access flow is this :

router.example.com ---> Cloudflare Tunnel ---> Pomerium IP --->Authentik ---> Router's Gui.

It works flawlessly. I don't often use it, but when I do, it helps. I also had it enabled for AdguardHome but moved to Technitium DNS which I prefer and that doesn't have the HTTP Headers so it's not fully compatible with Pomerium that I'm aware of.

What does Authentik do in combination with pomerium? I don't have it

[–] node815 2 points 7 months ago (1 children)

Authentik is my IDP provider so I put it in front of all my publicly facing Apps which support OIDC login. For example, I can log into my Portainer instance from an external network, but to do so, I log into Authentik First which sends it to my service.

For the apps which support HTTP headers, like I said, Pomerium acts as the service which passes my credentials to the device. I admit - Authentik does this also without the need for Pomerium, (through their flow settings) but I found Pomerium to be much easier to set up for this than Authentik and haven't looked back or felt the need to change it.

Ah I see! Thanks for the explanation, I have pomerium in front of everything using Google as IDP. Then if the app supports header authentication (like grafana) I get automatically logged in, and for those that don't I have to log in again (a bit inconvenient) I event went as far as forking one and implementing header authentication myself.
