I don't know - I'm sure every setup is different, but on my setup...

I tried to connect to the Internet from machine B but Zone Alarm on machine A caught the attempt and blocked
it, even though machine B was set up intentionally not to be able to use the Internet, (via home networking
wizard) and its in the trusted zone (in ZA). For what it's worth, here's my setup:

Machine A has Zone Alarm.
Machine B does not.
Machine A has two NICS, machine B has one.
Machine A has full Internet access via NIC #1
Machine A has full access to machine B via NIC #2 (Intranet)
Machine B has full access to machine A via NIC #3 (Trusted zone in ZA)

Perhaps I should try some different programs to attempt access to the net from machine B? It sure appears that
Zone Alarm is blocking its access, which is exactly what I wanted. I hope that's the case because machine B
has no AV program - my intent is to scan everything on machine A first, before B ever receives it.
