- USB Tether on Ubuntu 18.04: use VPN Hotspot and turn on USB Tethering.
See WiFi Repeater above for VPN Hotspot. All Network Settings will be done automatically probably by DHCP.
- BlueTooth Tether, using WiFi for outgoing path not Mobile Network.
Accidentally this was found and it worked. If you use WiFi and turned
on BlueTooth, the phone automatically turns it off saying you can not
use BT tether when you turns WiFi on.
- VPN Hotspot: this is for WiFi tether. See WiFi Repeater.
- OpenVPN Connect: This is for tunneling. (originally I can not
use ssh because ssh packet can go through the firewall, that is
why I started to use a "tunneling" by Open VPN Connect). Somehow
after this turned on, you can use BT tethering without the error
message above, but somehow again you can not use the tethering, so
turn the VPN connect off. Now you can use BT tether!
