domains on internal network

  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 router loopback is what you want.

    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.

      Thanks for posting this! I have the same router.

    Another name, depending on the exact context, is “hairpin NAT”. Should make googling with the specific router OP has easier.

    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 :/

  On my Fritzbox, I needed to add all my Subdomains to a list under:

  DNS Rebind Protection Your FRITZ!Box suppresses DNS responses that refer to IP addresses in its own home network (DNS rebind protection). Here you can specify exceptions for which DNS rebind protection should not apply. Do this by entering the complete name of the host (domain name including the subdomain) in the list.

  That’s under network settings, advanced. In case you have that.

  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.

  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.

  Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

  Fewer Letters	More Letters
  DNS	Domain Name Service/System
  IP	Internet Protocol
  NAT	Network Address Translation

  To bypass this problem you can add your domain (with all the third level ones) to your router, pointing to your internal IP

  I strongly recommend the NAT loopback route over attempting split-horizon dns.

  • EvilCartyen@feddit.dk ⁨4⁩ ⁨months⁩ ago

    I did go for that 😁 was a simple checkbox in the router settings.

      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

  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.

  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.
