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…
usually in your router settings you can change local DNS settings. you can set your domains and subdomains to point to your server’s local IP.
I strongly recommend the NAT loopback route over attempting split-horizon dns.
FYI, this is called “split horizon” DNS, where the location you get directed is based on the network you adk from. Make sure you have short TTLs set on your DNS records, or devices can have problems moving between networks and still having records cached from the prior network
Based on my setup, I use adguard to DNS rewrite all *.example.com domains to the IP of my Nginx proxy. I have the proxys setup on NPM. On my router I have adguard set as the home network DNS. Cloudflare is used as the external DNS so that the *.example.com domains work outside of my network (and point to thr Nginx server).
My setup is relatively basic, unraid dockers etc.
It depends if your reverse proxy is inside your home network or outside. It should work without any other configuration if you forward ports 80&443 from external domain with something similar to rathole and configure reverse proxy inside home network.
This is not an answer to your question about using the same url, but see this article, it might be helpful. Tl;dr: mdns + reverse proxy.
If your ISP provides IPv6, set that up. Everything will have a globally routed address, so your domains will work from your LAN and the internet. If you don’t have IPv6 available, get a free tunnel from Hurricane Electric.
