I know I don't want to open up any more ports than I have to, but you're right, that does sound like another alternative to setting up VPN.
Since I access more than just my pihole when connected to my home network. And because I want access to my home services, and don't want to open up access to the public, opening one port and connecting to VPN is the way to do it. I have one port opened up for my VPN, and in order to connect you have to have my IP or my domain pointed at the IP, and you have to have a Wireguard profile setup, and know what port is open. So that does help a tad bit with my security concerns.
Edit: how would I go about that if I felt so inclined? Any tips?
