Hi  I have a similar configuration, with two additional frame relay
connections to interstate sites  to enable CITRIX , CITRIX NFUSE and RDP
to manage the remote sever and desktops.

Hi Mario
 
I have an ISA and PIX firewall connected "back-to-back". Here is my
config:
 
LAN --> ISA --> PIX --> Internet
 
On the PIX's inside interface I have setup an access-list to permit ALL
traffic from the ISA's external interface. This is to prevent me from
having to duplicate all rules on ISA and PIX. There are more
configuration settings that need to be implemented but this is pretty
much the kernel of the whole matter.
 
The beauty of this solution is that for anyone to actively hack me, they
need to know BOTH firewalls. Also if there are any Denial of Service
attacks etc, I simply block those requests on my PIX without ever
troubling my ISA.
 
All in all I am very happy with our solution as I believe it offers me
the best of both world - flexibility and control!
 
Cheers
William R.
