Thanks for the feedback but the problem I'm facing (well let's say i'm
thinking of) is about the IP configuration in the 2 netowrk cards. In the
external nic I'll have to put the router ip address as the DNS and DG. So if
do that internet will work anyway even if I block the connection in ISA. I'm
not sure but as you said fiddling with it might give some clues to me. I'll
give a good try.

ISA is one complicated product, and this is really not the best group
for it (there are a number of ISA groups, 'staffed' with experts who
use ISA every day).

The external NIC does have the Internet IP address (which shoudl not
be a 'local' or 'private' address, but a true Internet IP.

The internal NIC has the local or private LAN addresses, usually it is
static (reservations work).

Rules in ISA cover what the NICs do, and how, and what passes and what
doesn't.

Be prepared for major issues and a very steep learning curve. I did
something similar to your setup, and it took weeks of work to get it
smooth and working. I was never happy with ISA overall, it is a bear
to manage (especially compared to my Cisco router/firewall).
