pi hole over internet

[tripaloski]

I have a pi zero running with pi hole and i want to know if there is anyway i can open a port so another person can use it over the internet (not LAN). If it is possible, is there a specific port for it?

Depends on how you want to grant access. You could open an SSH port and require certificate authentication to access the pi hole and port forward that but if you want to give them GUI access then I would instead setup a VPN and have them VPN and then connect into it that way with xRDP or something else.

I want them to be able to use the pi's ip as a dns to have adblocking like i do

So what you want to do is enable them to use your PI to do DNS lookups.

To do that you'd allow your router to pass DNS traffic (port 53/tcp and 53/udp) to your Pi.

Then have your friend point to your router for DNS.

But it's not that secure, you'd be opening up your Pi for all the world on port 53.

Might be better to just use another Pi on their network.
