I have set up a maintenance Network via OpenVPN. However, when I log into a computer (e.g. via remote desktop) and someone else is using it at the same time I have either to accept that she is able to access the VPN once I established the connection, or I need to force her to log off.
Both is suboptimal.
Is it possible to set ACLs to NICs? Or otherwise disable the access to the network for a certain user? I need it on XP and 7, but a solution only working for one of them is already a big enhancement.
