stlpaul, thank you for your wonderfully complete response. I will try this out within the next day.

As a side note, in my previous tests I was able to connect to my Cisco VPN over both Wi-Fi and Cellular (Tmobile in the USA, using the Tmobile "VPN Data Plan" which provides a public IP directly to my N900). Of course the connection would drop soon thereafter, but that is a different issue which hopefully your last post will help the community address.
