Routing + VPN in Windows NT 4 Server

[deather]

Hi there,

I'm setting up a Windows NT 4 Enterprise Server box.

This box (192.168.0.6) is connected to Internet through my home network router.

Also, it is connected to my school's network (using adresses on 10.42.0.0/16) via a VPN connection.

Every computers on my home network use my router (192.168.0.254) as their default gateway.

I'd like to configure my router (which is running Linux) to use this Windows box as a router to transmit packet to my school network via the VPN connection.

Things I've done:

- Activated the IP Forwarding in the TCP/IP Properties in Windows

- Added a route to 192.168.0.6 for 10.42.0.0 on my router

On my Windows box, I can ping machines located on my school's network.

However, from my router, I can't. Packets are just dropped.

I think the Windows box might be misconfigured.

I'm a newbie in Windows administration, and I think I'm missing something. That's why I'm posting here.

If anyone has a clue, I would really appreciate he tells me

Thanks in advance!

Cheers,

Thomas
