Using Internet SSL to connect to remote support
All the communications are handled through TCP sockets initiated by the HMC and use a high-grade SSL to encrypt the data that is transmitted. The destination TCP/IP addresses are published (see Internet SSL address lists) so that external firewalls can be configured to allow these connections.
Note: The
standard HTTPS port 443 is used for all communications.
The HMC can be enabled to connect directly to the Internet or to connect indirectly from a proxy server provided by the customer. The decision about which of these approaches works best for your installation depends on the security and networking requirements of your enterprise. The HMC (directly or through the SSL proxy) uses the following addresses when it is configured to use Internet SSL connectivity.
