I think this is what Hank is talking about. SOL connects at port 623,
but it may communicate over a different port later in the session.
However, ipmitool doesn't support communication over any port other than
623. So if SOL works for you w/o port forwarding, then this isn't your
issue.

Ridiculously easy VDI. With Citrix VDI-in-a-Box, you don't need a complex
infrastructure or vast IT resources to deliver seamless, secure access to
virtual desktops. With this all-in-one solution, easily deploy virtual
desktops for less than the cost of PCs and save 60% on VDI infrastructure
costs. Try it free! http://p.sf.net/sfu/Citrix-VDIinabox
