Currently we have a new Exchange 2010 enviroment configured next to the existing Exchange 2003 server:
2x CASHUB servers in a CAS array
2x Mailbox servers in a DAG.
2x LM-2200 Active passive in an 2 armed configuration.
The Exchange servers are placed in a different subnet as the clients. Also the CASHUB servers have the default gateway configured to to Loadbalancer. HTTPS VIP service (SSL Offloading) are configured with L7 transparency and Super HTTP. This works OK except that we are seeing some events in the eventvwr on the Mailbox servers. ( EventID 4002). The cause is probably that the Exchange Servers can't connect to the HTTPS VIP address for EWS in the different subnet.
How can we configure this without disabling L7 transparency? I understand that an option is to configure non-transparant, but does this mean that the connection is always comming from 1 ip address and therefore Load Balancing is not possible?
