We curerntly have a PIX in place at the edge of our corporate network. I am looking at purchasing Microsoft's Internet Security & Acceleration Server 2004 to add layer 7 filtering and some AD based rules to our filtering/routing. My question is how should I design this. Here is my thoughts and someone can fill in the gaps or suggest changes as they see fit:
***INTERNET***----->(public IP)**ROUTER**(public IP)------(public ip)PIX506e(any private unused network??????)----------(???????)ISA(10.0.254.1/28)------>Core switch (4507R)
Where I'm at a loss is between the ISA server and the PIX. Can someone plug in some addresses there that would work and tell me any other changes I'd need to make to get it set up properly.
Thanks in advance!
