Adding a published server interface - BlueCat Integrity - 9.3.0

Address Manager Administration Guide

Product name
BlueCat Integrity

In Address Manager, one of the properties of a server object is the server interface. A server interface includes the server’s Fully Qualified domain name and its IP address.

Address Manager uses two types of server interface:
  • Network—the default network interface that represents the physical interface on the server.
  • Published—an interface used to associate addresses that may be on the other side of a Network Address Translation (NAT) gateway or firewall.

DNS and DHCP deployment roles are assigned to a server interface rather than to the server object itself. If you need to publish a DNS server’s host or glue record that uses a different IP address from its network interface, you must add a published interface and assign the deployment role to this interface.

Published Server Interfaces with NAT and Dedicated Management disabled

Previously, with Dedicated Management disabled and NAT present between Address Manager and DNS/DHCP Server, the Published Server interface couldn't be configured with the same IPv4 address as the eth0 interface (which is providing services and management). Now, Address Manager can create and manage a Published Server Interface configured with an IPv4 address that's identical to the IPv4 address of the eth0 interface.

If you assign DHCP deployment roles to the Published Server Interface, the IP address of the Published Server Interface will be used as the failover peer.

Warning: If the published interface IP address associated with a primary DNS Deployment role is modified, the Address Manager server must be restarted before deploying to the primary and associated secondaries. Refer to KI-025343 on the Customer Care portal for instructions on restarting Address Manager. BlueCat recommends restarting the Address Manager server during a scheduled maintenance window in order to avoid service outages.
