I have some subdomains that go to my home address (I know I should put it through a VPS first but I'll get to that when I have time).

If I connect to example.domain.tld and DNS records point back to my own IP, where does that data go to reach back to my device?

Edit: thanks for the responses everyone

What you are looking for is something called NAT Reflection/HairPin NAT/NAT loopback.

When you search for a "domain.example.com" your router loops you back at your reverse proxy and all the traffic remains "internal". Your website will still be externally accessible (the ones you setup to be).

Here's a example of how to set this up on PfSense router.
