My environment consists of Windows 2003 servers, Cisco Pix 515e, & ISA 2004 server (2 nics - LAN, DMZ).
I have a webserver which sits in the DMZ. It has a public IP of 199.243.x.x, and a local IP of 192.168.100.x. I have configured the pix with the Alias, Static, & access-list commands and have no problem accessing the site over the web from external computers. My problem is that internal computers on the regular LAN (192.168.128.x) are being blocked by ISA from seeing the 199.243 address, they can only see the 192.168.100. (internal systems that go directly to the gateway instead of using ISA can access the 199.)
I have unsuccessfully tried to create a web rule in ISA to allow access. Is there a way to do this?
