hi Mac folks
my Mac Pro got three network adapters (2 x Gigabit Ethernet + 1 x Wi-Fi), and i prefer using the wireless connection to access the Internet and leaving the two wired connections for private file sharing and VM communication.
therefore, for the wireless connection, the firewall policy should be to disable all incoming traffic and allowing all outgoing access, while the wired connections should be firewall free or allowing specific application protocols. but it seems the Firewall options under System Preferences have no such a detailed control.
is it possible to apply different firewall controls on different adapters?
furthermore, what's behind the built-in firewall of Mountain Lion? PF or IPFW? is there any command line that may allow me to enable such particular firewall control?
any comments are welcome.
