I have opnsense, and it was pretty easy. I use DNS overrides and a local reverse proxy. When I’m on the home network, the local dns overrides point to the local reverse proxy. When I’m outside the home, public DNS records point to my VPS, which reverse proxies the traffic to my home machine. This way I’m only hitting the VPS when I’m outside the home. Much more efficient.

I think Side of Burritos’ youtube channel has a guide on how to set this up, but it’s fairly straightforward.
