I need help figuring out where I am going wrong or being an idiot, if people could point out where…
I have a server running Debian 12 and various docker images (Jellyfin, Home Assistant, etc…) controlled by portainer.
A consumer router assigns static Ip addresses by MAC address. The router lets me define the IP address of a primary/secondary DNS. The router registers itself with DynDNS.
I want to make this remotely accessible.
From what I have read I need to setup a reverse proxy, I have tried to follow various guides to give my server a cert for the reverse proxy but it always fails.
I figure the server needs the dyndns address to point at it but I the scripts pick up the internal IP.
How are people solving this?
By “remotely accessible”, do you mean remotely accessible to everyone or just you? If it’s just you, then you don’t need to setup a reverse proxy. You can use your router as a vpn gateway (assuming you have a static ip address) or you can use tailscale or zerotier.
If you want to make your services remotely accessible to everyone without using a vpn, then you’ll need to expose them to the world somehow. How to do that depends on whether you have a static ip address, or behind a CGNAT. If you have a static ip, you can route port 80 and 443 to your load balancer (e.g. nginx proxy manager), which works best if you have your own domain name so you can map each service to their own subdomain in the load balancer. If you’re behind a GCNAT, you’re going to need an external server/vps to route traffics to its port 80 and 443 into your home network, essentially granting you a static ip address.
You don’t need a static IP to host a VPN. You can do it using a dynamic DNS which updates the DNS records to match your IP when/if it changes. You do need a public IP though, so CGNAT goes straight out.
