I have kaspersky internet suite 2010. I have 2 networks one is Internet set as "public network" and other is my network card set as "Local network". By default i have protection from all intruders from outside the LAN, but i any PC from LAN can access my shared folders for example (or access my webserver). What i want to add is to limit all LAN users except one(or two) for accessing my resources. Can i set this configuration somehow? Should it be based on IP address or MAC address?
