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…
Ipv6
Depending on your gateway, you may be able to override the DNS settings for a few domains that you use internally
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.
To bypass this problem you can add your domain (with all the third level ones) to your router, pointing to your internal IP
I can’t remember exactly what its called, but something like router NAT loopback is what you want. I’ll have a look around. But if you set it right, things should work properly. It might be a router setting.

Thanks - I have an icotera i4850 router which claims to support NAT loopback, but I can’t figure out where to do it and it seems like the manual is gone from the internet :) Might have to ask my internet provider if they have a PDF somewhere.
Edit: D’oh, it’s a checkbox in the port forwarding interface! Thanks a bunch, didn’t know what to look for before your reply :)
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.
