Hi Tom, I have a similar setup and the only way i could get it to work was by including the external address range in the LAT. I logged this problem with Microsoft before adding the external addr to the LAT, even reinstall and reconfigured as per there instruction over the telephone. They could not get it to work without the private address range in the LAT. It works that way so I left it Warren -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxxxxxxxxx] Sent: Wednesday, April 02, 2003 3:56 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Publishing servers http://www.ISAserver.org Hi Badri, Check your LAT and make sure it includes ONLY your internal network addresses. Do NOT include any other addresses in the LAT.

NAT is performed by the router itself. I have installed 2 NIC cards in the ISA server, one facing the LAN and another facing the router. Both cards are configured with private IP address. There is a web server and exchange server behind the firewall and people need to access them from outside world. For this, I tried to configure server publishing rules but when I do that, I get an error message which says "The IP address specified is not external" and I get nowhere. If anyone of you have experienced similar problem or if you know the logic behind this, please help me.
