I am implementing the Exchange 2007 server with CCR. I am using four servers, one for ADS (catalog server), second one common server for edge and Hub, third and four for Mailbox server on cluster (CCR). All these servers are on same local network.
I want to configure HUB server on DMZ. Should I need two NIC in HUB server one for local network and one for DMZ? If this is the case then what will be the DNS servers for DMZ NIC?
Can anyone explain how to configure all these servers on network, IPs, gateway and DNS setting of individual servers?
