indirect Internet connection for Remote Support depends on the security and
networking requirements of your enterprise.
Hardware Management Console Direct Internet SSL Connection
If your Hardware Management Console can be connected to the Internet, and
the external firewall can be set to allow established TCP packets to flow
outbound to the destinations described under “Server address lists,” you can
use a direct connection between the HMC and the Internet. The use of Source
Network Address Translation (SNAT) and masquerading rules to mask the
HMC’s source IP address are both acceptable.
Hardware Management Console Indirect Connection with Proxy Server
For the Hardware Management Console to communicate successfully, your
proxy server must allow connections to port 443. You can configure the proxy
server to limit the specific IP addresses to which the HMC can connect. See the
“Server address lists” for the IP addresses to use.
Server address lists
Whether you are using a direct connection (the HMC only) or an indirect connection
(with a proxy server) for Internet access, the HMC utilizes the following IP
addresses and port 443 for all Internet activity:
The following IPv4 addresses work with, and are required for, RSF connection to
Hardware Management Consoles using Licensed Machine Code at version 2.10.1
or later.
Table 4. LMC 2.10.1 and later IPv4 addresses
LMC 2.10.1 and later IPv4 addresses
129.42.26.224
129.42.34.224
129.42.42.224
Internet Protocol version 6 (IPv6) vastly extends the range of available IP
addresses. Although IPv6 is not required for remote support facility connection, IBM
now offers the capability to migrate to IPv6. The following IPv6 address table is
provided as reference. Otherwise use the IPv4 addresses shown above.
The following addresses work with Hardware Management Consoles using
Licensed Machine Code at version 2.10.0 or later for RSF connection with IPv6.
Table 5. LMC 2.10.0 and later IPv6 addresses
LMC 2.10.0 and later IPv6 addresses
2620:0:6C0:1::1000
2620:0:6C1:1::1000
2620:0:6C2:1::1000
The following Internet Protocol version 4 (IPv4) addresses work with Hardware
Management Consoles using Licensed Machine Code at version 2.10.0 or earlier.
Any HMC being installed with Licensed Machine Code at version 2.10.1 or later
should use the IPv4 addresses in Table 4.
