I’ve not done much with external access in the past, but I’m playing with Tailscale and it’s pretty neat. Wondering if I can configure it to work like my local access does:

  1. I use Nginx Proxy Manager to set easy subdomains for my services, I.e. service.mydomain.com
  2. I use AdGuard Home and have a redirect for *.mydomain to that NPM
  3. This works great internally, which is all I’ve really used it for.
  4. I’ve got tailscale working and I can go externally to server.wackyname.ts.net:serviceport.
  5. what I’d like to do is have tailscale somehow use the same internal dns/npm info so when I’m on my tailnet service.mydomain.com still works.
  6. But no other external access, said subdomains do nothing off tailnet.
  7. Mydomain.com is an actual domain I own. General DNS is at Cloudflare right now (main domain was pointed at a hosted site previously, but that’s not needed anymore)

Any way to pull this off without a ton of complexity?

    Do a DNS rewrite at AGH, but instead of the LAN IP make it the Tailscale IP of your NPM machine. Then configure AGH’s IP address as one of the global nameservers on your Tailscale admin panel

    Delete all A/AAAA records on Cloudflare, only use it for registrar purposes and the occassional certs authentication.

      Wouldn’t that prevent any devices that don’t have tailscale from using it even locally?

        Yes.

        If you want to access your NPM stuff on both Tailscale and LAN, either:

        • Advertise a subnet route for your LAN range, configure Tailscale devices to use it, and use your LAN IP on the AGH rewrite, or
        • Split Horizon: Have your DNS respond with a Tailnet IP when it’s queried from the Tailnet range, and respond with a LAN IP when queried from LAN. AGH cannot do this, but other software like Technitium can
