So maybe I am missing something obvious, but here goes:
I’ve got a small server at home, and I have simply.com pointing various domains to it. Works fine, nginx routs the traffic where it needs to go.
But whenever I am at home and connected to wifi I have to use the internal address and port to reach my server, e.g. 192.168.0.192:8096 for my Jellyfin server. If I use the public URL at home, i hit the login page to my router.
This is annoying when I use apps, as I need to switch between the public URL and the internal address as I come and go from my home…
What are my options for doing something about this? I want to use the public URL at home too…
You may have to set up split zone DNS so names resolve to private IPs when at home but resolve to public addresses when not home.
I use pihole as my home DNS to do that
This is what I do as well. I use terraform/tofu and add two entries whenever I add a new domain, one for my external provider and one for my pihole pointing at my internal IP for my home network.
