My question is essentially: How can I enable Outlook users to use Outlook via HTTPS over RPC externally to failover and connect to a different Exchange 2007 Hub server on a separate datacenter for redundancy?
I've implemented a new Exchange 2007 environment with 2 x Hyper-V nodes each running a VM for clustered Mailbox CCR and another for Hub Transport & Client Access roles. I want to move one of the boxes into our offsite Datacenter rack for redundancy. The sites are link by a private fibre connection and will be fully routable internally. I understand how to keep the CCR working between the two sites and that the Transport roles should work pretty much automatically. I also understand that I can use Windows NLB to failover between the Hub servers internally. What I'm not sure about is how I can make this work externally when the Hub servers will both have different static IPs?
