NAT Configuration

Static NAT mappings must be defined for every Sun Management Center NAT host.

Dynamic NAT mappings are not supported for Sun Management Center 4.0 operation across the NAT.

Because several undefined ports are used by Sun Management Center, Sun Management Center does not support the ability to specify port restrictions for Sun Management Center NAT support. These ports include SNMP, probe, RMI, and console integration.

To support operation in a NAT environment, NAT enables Sun Management Center 4.0 software to use names rather than IP addresses to identify and communicate with other Sun Management Center hosts. The name must be a host alias that can be resolved to a valid IP address through standard naming services. This name also must be resolvable to the appropriate IP address in the relevant addressing realms in which the Sun Management Center components are deployed.

Thus, common host aliases for all Sun Management Center NAT hosts must be defined in the host maps of all addressing realms in which Sun Management Center components are installed.

The host aliases must be defined in the standard system host maps that can include such things as the files, for example, /etc/hosts, NIS, NIS+, and DNS. For the remainder of this chapter, the common host alias is referred to as the NAT host name.
