Check if you're aiming to send traffic or change its path. I'm not sure why pihole exists.
It seems you're referring to a redirection related to Pihole functioning as a DNS resolver. Could you clarify what you'd like to discuss further?
IP to IP isn't related to DNS. You could easily do this using a VPN and a dedicated connection for your static IPs at home. I had a setup similar to yours, but it involved routing a static /56 IPv6 allocation via 6to4 tunnels through an IPsec tunnel over a v4 network.
