PPTP and Routing

Hello!
Some Routing Questions:
Assume we have the follwoing network:
Internal1---InternalRouter---Internal2---PPTPRAS-Server---FW--->
<---Internet---ISP---Windows_PPTP_Client
When I use an ISP that does not support PPTP, I have to use the Microsoft
VPN Adapter. To reach the Network Internal1 I have
1) to set the "Default Gateway" through the PPTPRAS-Server in the
PPTP-Dial-Up-TCP-Properties. But if I do this, I couldn't reach my
PPTPRAS-Server for my PPTP-Tunnel, because I would need a Default Gateway
through my ISP for it. But the ISP Default Gateway incommodes with the
PPTPRAS Default Gateway. Finally this would not work...
2) Manually set a route on the client for internal1 network through the
PPTPRAS-Server. But how to do this automatically? I dont' want use static
routes (i.e. through a startup script). First I got a problem if I don't
know all my internal networks (i.e. on large sites running ospf or
something). A further problem with static routes would be, that you always
would have the routes - even if your are not comming over the
internet and you are connected to one of the internal networks (like
notebook users "road warriors")...
So my question: is there a possibility to set up routes if you connect
with pptp and to delete the routes if you disconnect? And maybe you could
administrate the routes only on the PPTPRAS-Server?
yours sincerely
M. Hofmann
