You do not lease an IP address on the local network, you just encrypt the traffic to and from a given IP/Netmask.  This makes "roadwarrior" dialins a bit tricky.  If you have a static IP on the Win2k box, then it's very easy to set up the IPSec tunneling.  (Well, not easy, perhaps, but doable).  If you want to connect roaming dialin users, then you need to jump through some hoops, or just use PGPNet, or some other IPSec client software to manage things.

By problem is currently that i have multiple clients behind a linux box 
doing NAT/masquerading. so when the clients get to the pptp server they 
all seem to have the same ip address and hence pptp will only create one 
tunnel per ip and  ALL clients will go thru this, which creates a big 
mess! i was hoping that we can either change pptp to allow mutliple 
tunnels per ip-pair or that i can use FreeS/wan somehow.

The clients are a mix of win/2k/98 they connect to the linux box which 
will serve them an ip address via dhcp, and then the box will NAT all 
their packets which are then forwarded to the pptp server. and that is 
where i get into problems...

i can explain why i am doing all this in case you are interested.

Also, you have the bonus that it interoperates with other IPSec implementations (an advantage you don't have with vtund).  I set up FreeS/WAN for connectivity to our backside LAN at the colo center (connecting to a Netscreen100 firewall), and since then have been easily able to add in tunnels for my network at home (FreeS/WAN) and to a coworker's Win2k box.
