We have an Exchange 2007 system on an internal network connected to an ISA 2006 server ( A NIC on the ISA server is connected to this internal network ).
We are implementing an Exchange 2010 system on a different network. In other words, the internal subnet that our Exchange 2007 system is on, and the subnet that the new Exchange 2010 system is on are different subnets.
We would like our ISA server 2006 system to include the subnet our Exchange 2010 system is on as part of the internal subnet it is protecting.
Is this possible? If so, any idea how this can be accomplished.
Thank you all in advance for taking the time to read/reply to my question
