There are some very specific ports that have to opened on the firewall
for the call home to work. IBM does not try to access from outside. I
have to see if I have the docs around somewhere. But an IBM IPR or CE
should be able to provide the exact setup. I know of many users who
access the HMC on the network, and remotely via VPN. Never any issues.

IBM has told us that would like us to move our HMC so that they can change the call home
server to use the Internet. I am sure there are some white papers and articles about
security. Our security dept. is concerned about putting it on the internal network since
it is just another Linux box. Can anyone point me to some articles or share their
experiences? I have been reading the "Intro" book on the HMC and it discusses
some of the security issues.
