That link doesn't work.
MetropleX Using the Owner profile's VPN for tethering/hotspot clients or using the Owner profile's VPN for other user profiles
Not sure that would be the popular use case.
We do have a feature request filed about adding a way to route tethered clients through a VPN, but we don't want to implement something that's worse than running a separate VPN on each of those clients. There is no obvious good way to implement this. It may be rejected instead.
The replies from 24coding reflects the true benefit and the most common use.
- the network operator can no longer see that the GOS user is running a hotspot. (some providers still charge extra)
- not all devices can be operated as a VPN client and therefore currently expose the IP that is directly linked to the GOS user. (most common reason this is needed)
- People with whom you share the hotspot do not necessarily have a VPN or care about your privacy.
I'm not sure why the assumed use case is to tether another device that can be a VPN client.
There are loads of devices that I'd like to tether that aren't running an OS that I can install VPN software.
