I am trying to figure out how to block access from a certain remote computer to our network. The client computer sometimes connects via the VPN and sometimes only through Outlook RPC/HTTP.
The user still needs to connect to our network but I only want them to connect through a standard company issued computer they already have, not a personal one.
I tried to find the MAC address on the ASA 5520 using ASDM 6.1 when the client has an open VPN session but it seems that information is not available.
Any other way I can block access to our network from non acceptable computers?
