[pptp-server] Tunnel in a tunnel?

[Hein-Pieter van Braam]

HI all!

I have a problem: here in holland we have an ADSL connection called MXSTREAM 
(it suxx) anywayz to connect you first have to make a VPN connection to your 
"router" (or whatever it is) and then complete a logon script on the main 
site of mxstream. 
Now there is a small company that uses mxstream and have 2 locations and they 
want to connect them using a VPN.
my question: is it possible to make a VPN connection over that existing VPN 
connection to that other location through ANOTHER VPN connection?

(seeing stars yet ;-) )

thanx people!
