Yesterday I thought of a way to use Pi-hole when I’m not on my home LAN but on a public Wifi network.
There are many guides to use VPN to reach your Pi-hole at home.
They can surely be done but imo there are too many things that can block access to the Pi-hole. Like firewalls or VPN server being done when it should be up. And more.
Too risky for me.
Also thought of taking a RPI/Pi-hole with me together with my laptop. I think it can be done but how about power supply to the RPI?
So finally I installed Pi-Hole on my laptop (Linux). Not as dedicated Pi-hole but added to the OS.
Are there people who done this? Next week I can test this.
