Old computer, or Raspberry pi with proxmox and pfsense on it. The positive thing is that you can run other servers as well (pi-hole for example for network wide blocking ads)

Sorry for the late reaction. I found a solution in cloudflare tunnels. Works, and easy enough to understand.

I discovered this one too. Don’t care about the downside as long as it works and is easy a ough to do…And it is, worked right out of the box. The only problem I have now is that my website (hosted on the servers of a domain provider) is not accessible anymore. Tried to redirect to the correct ip, but it’s not working. I have an nginx server too but for some reason that ip is also unavailable, while the one from my jellyfin (which is on the same proxmox) is 🤔

So if I want to go to www.mydomain.com/pihole to go to my pi-hole instance, I would create an A record containing the internal IP of pi-hole and an MX one to configure the subdomain (www.mydomain.com/pihole), is that correct?

Lots of servers running. Main System is proxmox. I have an Ubuntu server running on that with docker installed which runs about everything (pi-hole, nginx, jellyfin, radarr, sonarr, (even) Firefox, and more). So end goal would be to go to www.mydomain.com/pihole to access pihole, to www.mydomain.com/jellyfin to go to jellyfin and so on.
