HI TOMY,

I WANT PUBLISH AN SERVER OWA 2003 THAT THIS LOCATED IN A NET INTERNAL , BUT FOR THAT I AM USING ISA SERVER 2004 AS FRONT - END LOCATED IN A DMZ WITH SINGLE INTERFACE BEHIND A FIREWALL PIX WITH NAT ENABLED. I AM NOT GETTING WITH THIS ARCHITECTURE TO PASS THE CREDENTIALS OF AUTHENTICATION FOR OWA. HOW SHOULD I PROCEED?

PIX EXTERNAL WITH NAT --> ISA 2004 ( ONE NIC)--> PIX INTERNAL --> OWA 2003

BEST REGARDS.

You need to fully deploy the ISA Firewall in full firewall mode to fix the security problems with the PIX. Single NIC "hork mode" is not a secure configuration, and neither is the unprotected PIX. Get the ISA Firewall correctly configured with two or more NICs to protect your network.

HTH,
Tom
