Eric,
According to Zone Alarm support it will work with ICS that runs on the same
computer but not with NAT software on the same computer. Check their
support page: http://www.zonealarm.com/support_za_ics.htm
I was running NAT so it would not work on my network, installed on the
gateway computer, even with IP addresses or computer names added to the
local zone. As I remember, Zone Alarm 1.0 would not support ICS either. If
you are running NAT then you will have to upgrade to Zone Alarm Pro to
install Zone Alarm on the gateway computer. I had to many problems with ICS
and use Sygate on my network. I could not get Zone Alarm 1.0 to work
installed on the gateway computer at all, with Sygate running on the same
computer. It would not allow any computer except the gateway to access the
internet.
