I can access a VPN on my phone.  

I can access wifi on my phone.

I can tether a computer to my phone while it is connected to wifi and a VPN.

I can access the internet on the tethered computer.

But, the tethered computer doesn't appear to be going through the VPN.  Google cannot be accessed.

I want to use the tethered computer with the VPN on the phone.

The computer I want to use is a Chromebook.  It won't do much until I complete the OOB setup.  So, I cannot put a VPN on the computer.  The computer must access the internet through the VPN on the phone to complete the setup.

The least infeasible solution seems to be a border run to Zamiin Uud during the mid-Autumn break, but the crossing might take over four hours each way during the holiday, the shuttles across no man's land aren't free, and I get the idea that it's dicier than Poipet.

The most feasible might be if someone else who lives in Inner Mongolia is going to Hong Kong or Bangkok for the break.  That person could do the setup for me.

My wife will kill me slowly if I order another damn computer; it's best I make this one work.

Any help would be appreciated.
