Are you looking to set up the server end of the IPSEC connection as 
well, or just the laptop?  Which IPSEC implementation are you 
using?  I have been researching this using Openswan on the server, 
and Microsoft's L2TP client on the laptop (if the laptop runs 
Windows).  The book "Building And Integrating Virtual Private 
Networks With Openswan" by Wouters and Bantoft helps with setting up 
the server end of things, but seems to be lacking in how to set up 
the roadwarrior part of the connection (if using Windows).  If you 
are using Linux on the Laptop as well, then this book will help 
you.  There are keywords you can use in your setup file that take 
care of the dynamic IP addressing.
