Module Configuration Propagation (MCP) reads and writes to the Sun Management Center web server through a single predefined port. The default port is 8080. If the web server sits behind a firewall, MCP has no problem reading from the web server, but will have a problem writing to the web server. Once the web server has established a connection with MCP, the server arbitrarily assigns a port to do its job. You cannot specify which port number the web server should assign.
Workaround: None.
