Gareth,

Can you give me more info off of the list? What I would like to see is
the *EXACT* commands that you are using for the route add. The route
command below looks a little incorrect. I use a net route rather than a
host route (as below), and the Linux client works fine for me. 

ex: route add -net 10.0.0.0 (my subnet at work) gw 10.100.0.2 (internal
interface of my pptp server) netmask 255.0.0.0 (anything going to
10.x.x.x) dev ppp0 (or ppp1, ppp2, whatever the pptp device is). 

Kenny
