Each Ethernet interface can have multiple IP interfaces assigned to it. An IP
interface is a logical construct that associates an IP address and hostname with a
physical Ethernet interface. If you decided to use both the Data 1 and Data 2
Ethernet ports, you need the IP addresses and hostnames for both connections.

IronPort recommends using one of the physical Ethernet ports to connect directly
to the Internet for the purposes of receiving inbound email through public
listeners, and using another physical Ethernet port to connect directly to your
internal network for the purposes of relaying outbound email through private
listeners.

The following information is required:
•
A name (nickname) created by you to refer to the IP interface later. For
example, if you are using one Ethernet port for your private network and the
other for the public network, you may want to name them PrivateNet and
PublicNet, respectively.

IP addresses within the same subnet cannot be configured on separate physical
