Hi all,
I would like to use a linux phone with Ubuntu Touch or PostmarketOS to make a sort of mobile modem which, when my laptop connects to the phone's hotspot, would have Pihole for DNS and a VPN. Is this possible, and which general steps would you recommend to go about it? I have installed PostmarketOS on a Poco F1 and connected to my VPN using openvpn in the terminal, but then when I open a browser on the same phone and check my ip address it shows the address of the wifi I'm connected to, not the VPN. So it seems I have no idea about the architecture of this endeavor.
I hope to have this working by Christmas when I go to visit my parents. The intended internet connection would be
home wifi ---> linux phone [some level of privacy]---> my laptop wifi
Thank you in advance!
