[pptp-server] Problem: Fowarding PPTP

[Jose de Paula E. Junior]

I have 2 nets.

1 of then is the 10.0.0.x network where the 10.0.0.1 machine is a pptp 
server, and is too a NAT that conects the people to the internet. (the 
people connects in the VPN server and then can go to the internet)

The other is a network in a building,  This network uses the net 10.0.40.x.

There's a Linux 2.4.2 box acting like server to this building, it uses a 
ethernet card(eth0 - 10.0.40.1) to connect to the 10.0.40.x net and a 
wireless card(eth1 - 10.0.0.17) to connect to the 10.0.0.x network.  
 From the server I can make a VPN connection to 10.0.0.1

The problem is: there's a way to make the machines in the 10.0.40.x 
network (mostly windows) access the PPTP server in 10.0.0.1 and navigate?

A little schematic:

---------------
| 10.0.40.x network  |
---------------
        |
        |
-------------------
|  eth0 = 10.0.40.1            |  Server on the building
|  eth1 = 10.0.0.17            |
-------------------
        |
        |
------------------               --------
|  10.0.0.1                       |-------|  Internet |
|  VPN Server                |               ---------
