Security requirements at a remote data center might not allow connections to the WebSM related ports needed for the p4 or p5 HMC graphic user interface (GUI).

Answer
You can use the popular freeware SSH client , PuTTY, to tell a remote secure shell (SSH) server what ports you want forwarded over an SSH connection. If you use PuTTY, the following example would allow you to forward most of the WebSM related ports that the HMC GUI works with. All the remote traffic would be over the SSH connection so everything would be encrypted. While port forwarding does technically work over SSH and the current versions of HMC have sshd configured to allow port forwarding, the following is not a supported way to connect to WebSM (which simply means if you can’t get it to work, IBM support is not obligated to help).
- Configure a PuTTY session for your HMC and save it.

- Run regedit

- Navigate to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions

- Open the session you saved and find the PortForwardings key.

– Paste in the following

L80=localhost:80,L657=localhost:657,L9090=localhost:9090,L9735=localhost:9735,L9940=localhost:9940,

L30000=localhost:30000,L30001=localhost:30001,L30002=localhost:30002,L30003=localhost:30003,

L30004=localhost:30004,L30005=localhost:30005,L30006=localhost:30006,L30007=localhost:30007,

L30008=localhost:30008,L30009=localhost:30009,L9443=localhost:9443,

– Save the key.

When you are ready to connect to WebSM on the remote HMC, you first use PuTTY to connect to the HMC using SSH and then launch the WebSM client and connect to localhost.
