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?

My IPv4 connection uses CGNAT, so I use a VPN to access my server. I also have IPv6, so I have a couple of things directly accessible over it in case the VPN drops for some reason. I do have dynamic DNS set up, although it’s not really necessary. My IPv6 prefix doesn’t seem to change unless I change the DUID on my firewall.
