I have an old Fritz Box 3370 that I'd like to use as internet router. It only can connect via DSL or IP, not via Wlan or LTE.
So I'd like to have connection via Raspi and an old Android phone (with broken screen , so I need USB for the mouse, no USB tethering).
Which tutorial would I use for current Raspbian Strech? Setup should be on the console.
As I understand, DHCP serving is done by the phone. So the Raspi would just have to route ip, wouldn't it?
