We are trying to setup a backup plan for the following:

Diagram Path:
Webserver<->DMZ<->PIX<->hub<->ISPRouter<->ISP<->Internet

Where 207.xx.xx.02 NATs to DMZ IP address and 205.xx.xx.05 is ISPs webserver at ISP location.

Customer has a website that will point(ISP DNS)to a public address 207.xx.xx.02. An alternate host is 205.xx.xx.05.

Should 207.xx.xx.02 fail, is there a way to redirect requests going thru the ISPRouter(located at customer site) to go to 205.xx.xx.05 (located at ISP site)?

We already thought of using the DNS Round Robin Method. We want to see if there is another method that we can use in a fast way. DNS changes can take up to 24hrs to propagate thru the internet. s-)
