A typical configuration allows Web clients on the Internet to access CM Server through a firewall. Communications between CM Server and the hosts supporting the Web product use the HTTPS protocol and are secured by SSL. Communications between CM Server and the hosts on a private intranet use ordinary remote procedure calls (RPCs) and are not secure. Ordinary RPCs cannot communicate through a firewall, so you cannot place a firewall between CM Server and the host servers.
In a typical configuration, for example, the Web address is https://hostname/application_directory_name
In this example, the hostname is the name of the CM Server server host and application_directory_name is the application-specific directory name. The default port for communications between Web clients and CM Server is 12080. The default port for communications between CM Server and the Administrator console in WebSphere® Application Server is 12060.
