I currently have a PIX and ISA 2004 configuration that I would like to change as I move to a ASA 5510. Currently my internal network 10.2.x.x has a dual nic ISA 2004 server with the internal nic having a 10.2.x.x address and the other nic have a 10.1.x.x address. I then have a switch on the 10.1.x.x network that connects my ISA box to the PIX and then the outside PIX nic has a public address. I would like to take the ISA box to a single nic having a 10.2.x.x address as well as the ASA. I want all of my HTTP traffic to go through the ISA box and know that I can control this via access rules on the ISA box to only allow traffic from that address (correct ?). Also in my network I have numerous other buildings connected to the central location via a Cisco 3600 router. I am assuming that I will need to set the default gateway for the router to the internal address of the ASA server. Finally, I am looking for any sample configurations for the ASA for what I am attempting to accomplish.
