Jason,
This sounds a lot like a problem we had here with our VPN - users in
Munich/Paris not being able to get to thier servers when they connected to
the London office via VPN. So, can you tell me...:
What kind of device do you have in between all the subnets?
What are the IP addresses of said router?
What is the IP address and mask of the VPN device? (and what kind of device
is it?)
Cheers
Gerald

Please respond
to "NT System
Admin Issues"
This is a somewhat involved problem, so I'll try to give as much detail
as
possible to help paint a picture.
We've got several internal subnets. (i.e., 192.168.1.x, 192.168.2.x,
192.168.3.x and so forth)
We have a firewall device terminating the VPN connections. The pool of IP
addresses assigned for this are in our primary subnet. (192.168.1.x).
By default, the W2k PPTP client adds a route to the network your VPN device
is assigned. So, now all traffic destined for 192.168.1.x via the VPN
connection works great.
However, any communications to the other subnets will try and find their
way
using my default route. My ISP.. and they won't get anywhere.
I can remedy this problem manually pretty easily:
ipconfig /all
get IP address of VPN interface
route add 192.168.0.0 MASK 255.255.0.0 [ip address of VPN interface]
However, This is not a sufficient task to ask my remote end users.
I'm looking for a way to automatically execute this command after the VPN
connection is established.
Even a batch file they can run manually would be acceptable.
The problem I've run into, is that Windows does not have very advanced text
handling routines as commands. So stripping the IP address from ipconfig to
save into a variable is nearly impossible.
Thoughts, ideas, suggestions?
Jason
