I have several machines that are not connected directly to the internet. They use a HTTP(s) proxy that allows them to visit websites.
The machines are currently not activated because of this. The machines are loaded with a GVLK key and the KMS server is in another network.
What would be the correct approach to activate those machines? I can temporarily connect them to internet, but I read online that GVLK tries to reactivate every 7 days which is unacceptable.
I tried setting up a linux machine that is connected to internet and relays KMS requests to the actual KMS server, but that does not work either unfortunately.
