You can't run the VPN on the router if you don't own the router, which means that you can't protect your device's traffic when you're on the go, using mobile hotspot, or connecting to an ISP-supplied gateway without additional hardware.
Frankly, a fixed "Internet" Service Provider that doesn't provide you with a router (and leaves you the possibility to use your own) and a /48 IPv6 prefix should have no legal right to call that service "Internet" (in a similar way that Internet neutrality has to be legally respected) :
(Mobile cellular Internet seems to be harder, but is there any reason why user's cell-'modem' can't handle the routing of successive /64 connections ?)
If I have a second phone (e.g. Android( running a hotspot, and I enable a VPN on that phone, will the hotspot / shared internet also go through the VPN, or will the hotspot bypass it?
