Address Manager can have multiple IP addresses and thus multiple interfaces assigned to its Ethernet connection. These interfaces can be used to provide extra functionality such as DNS views, xHA, and NAT traversal.
Beyond the default or physical interface used on each server, there are two other kinds of
interfaces:
- Virtual interfaces are used and managed by Address Manager to represent DNS and to address Address Manager appliances in an xHA configuration.
- Published interfaces are used to associate addresses that may be on the other side of a NAT gateway or a firewall. These interfaces associate data sent to their IP address back to the appropriate managed server. Published interfaces can be added for single servers and xHA clusters.
During an import, Address Manager always assigns the deployment role to the network interface, even if the server is on the other side of an NAT device.
