Is domain authorization possible outside the local network?

Question

VPN

Good afternoon.
There is an office, half of the employees sit and work stationary, half will either take laptops or go on business trips. There is no domain yet, but it will be.
Actually, the question is whether it is possible to organize an automatic connection to the VPN tunnel when an employee leaves the office, and vice versa, when he connects back to the corporate network, he worked without a tunnel. Provided that the tunnel will rise before authorization of the user on a laptop.
The main thing is automation, so that the user does not interfere in this process.

Answer 1

I don’t know the nuances, but in our% companyname% it seems to be the case, if little people leave somewhere with a laptop, then they are given a vpn to access the domain and resp. to the shared daddy in it.
