How and with what to create this?

Question

VPN

I'm sitting through a VPN with a dynamic address and it takes about 5-15 minutes to update the domain.
How to make it so that when disconnecting from a VPN, the Internet has access only to vpn?

Answer 1

Well, bone tongue. TS, I barely understand what you want
Through the firewall, Deny all packages that go outside the vpn, and only allow your client to connect to the Internet, for example, OpenVPN. I do not recommend using the vpn protocols built into Windows, because, frankly, they are no longer so safe.
