I am looking to use DNS for fail over. We have 2 sites, site A and B. Site
A hosts all of our servers including apps such as GW Web access and
Citrix. Site A and B are connected via a fast Ethernet connection. When
Site B connects to a web app at site A it uses the internal IP address via
the Ethernet connection.My question is when the Ethernet connection
between the sites goes down we need Site B to get to Site A using external
Ip's. Essentially I need 2 IP's for 1 host, can I do this? I tried to
create a second A record with the same name, but different IP and it tell
me object already exists. Any ideas on how I can get this to work?
