Hi all... Our security concept is implemented with a PIX firewall. The device has three interfaces named "external", "DMZ" and "internal". Since we have a whole B-class, all adresses within our registered range are in my LAT. Works pretty well for my web proxy clients to use the web proxy service. Well, I want to use some more features of our ISA server than just the web proxy service. I already installed integrated mode and physically have two NICs on the machine. As I have been testing and clicking around I noticed that some features (e.g. server publishing) requires "internal" and "external" addresses. Since our DMZ is implemented via routing (its a whole subnet of our B-class) ISA server does not let me publish any servers because all NICs are on the same subnet (the DMZ subnet). Is it possible to configure ISA server to recognize our DMZ subnet as external? Yours, KK -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln!
