I have a network currently using ISA 2004. I want to move them to PIX. The only problem are two servers. One server runs a site called www.mydomain.com. The other site (hosted on an Exchange server) server.mydomain.com. As far as the outside world is concerned, all of the traffic for mydomain.com goes to the ISA (198.88.238.x). Once it hits the ISA it looks at the header and determines which inside server to send it to. So - my question is, can this be replicated on a PIX 501? I tried doing a translation rule but it didn't seem to do what I wanted. To make a long story short, when traffic for www.mydomain.com hits the PIX I need it to go to server A. When traffic for server.mydomain.com hits the PIX I need it to go to server B.
