Assigning Network and IP Addresses
This appendix describes general rules on networks and IP address assignments, and it presents some
strategies for connecting the Cisco IronPort appliance to your network.

Ethernet Interfaces
The Cisco IronPort X1050, C650, and C350 appliances are equipped with as many as four Ethernet
interfaces located on the rear panel of the system, depending on the configuration (whether or not you
have the optional optical network interface). They are labeled:

Selecting IP Addresses and Netmasks
When you configure the network, the Cisco IronPort appliance must be able to select a unique interface
to send an outgoing packet. This requirement drives some of the decisions regarding IP address and
netmask selection for the Ethernet interfaces. The rule is that only one interface can be on a single
network (as determined through the applications of netmasks to the IP addresses of the interfaces).

network (as determined through the applications of netmasks to the IP addresses of the interfaces).
An IP address identifies a physical interface on any given network. A physical Ethernet interface can
have more than one IP address for which it accepts packets. An Ethernet interface that has more than one
IP address can send packets over that interface with any one of the IP addresses as the source address in
the packet. This property is used in implementing Virtual Gateway technology.
