VPN over Personal Hotspot
VPN issues using Personal Hotspot
I am running iOS 11.2 on my iPhone 7 Plus and use the Personal Hotspot to connect my Linux laptop to the internet using my 4G mobile internet connection.
I have a VPN set up on the laptop but this will not connect. I also have the VPN set up on my iPhone. If I connect the VPN on the phone this becomes shareable on the laptop through the Personal Hotspot.
I would assume the same would work with any device connected to the hotspot. I hope this information is useful
