Openswan - XP->Linux tunnel

Hi
Can anyone help with an example of a Windows-XP to Linux Openswan
config ? What I would like to do is to have

XP(192.166.100.10) <-- Wireless -> Linux(102.168.6.100.11)+subnet
192.168.101.0/24

I want to create a tunnel so that the XP machine can 'see' the
192.168.101 subnet but that traffic will be IPSec'd over the wireless
connection.

I have managed to configure XP<->XP tunnel and also XP->Linux IPSec
connection i.e. not a tunnel with a visible subnet.

I cannot work out much from the Openswan doc/wiki, can anyone provide
any configs that work ?
