As long as IPSec isn't enabled on the external NIC, ISA should operate just 
fine, all other things being equal.

              Ok here is the scenario.  

   

  1.       Internal Network is all running with IPSec.

  2.       Trying to setup ISA to act as firewall for the network

  3.       ISA is installed on a server with IPSec enabled on the NICs

   

  The question I have is this all possible?  Or is there something I am over 
looking here.  Now I have set up a simulation of all this in my lab for 
testing.  There is an AD with 5 workstations, an ISA server with 3 workstations 
with IIS running on the other side of the ISA.  I have enable IPSec on all 
machines on the inside of the network like we want, and no IPSec on the 
machines simulating the Internet.  

   

  Suggestions are always welcomed.
