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 can’t remember exactly what its called, but something like
routerNAT 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.Found it: https://community.tp-link.com/en/home/stories/detail/1726
I think the term often used is “NAT reflection”.
Never heard that term, but its a very obscure concept, so wouldn’t surprise me if it had multiple names. Probably vender specific names?
Seems quite a few people havent heard of it, hence a lot of the split DNS answers :/
Another name, depending on the exact context, is “hairpin NAT”. Should make googling with the specific router OP has easier.
