access shared file behind ISA using VPN

Hi All,

I have a VPN connection between tow ISA server. How can I access files behind ISA server: see following diagram:

Fileserver------ISA2 (VPN)--------------------- ISA1 (VPN)-----------------PC1
10.10.1.1          VPN IP:192.168.1.1            VPN IP:192.168.1.2            10.10.5.5


PC1 can access files on ISA2, but how can user from PC1 access share files on Fileserver?

thanks

What subnet masks are you using for the 10.10 networks at either end?

subnet mask is: 255.255.0.0
the 192.168.0.0 is the ip that is created by VPN

Take a moment to understand that I have a life outside of experts-exchange. Like you, I have a day job and we respond to questions after we get home - in our own time - for nothing - to help you. If you want to dump the question - be my guest.

So you have the 10.10.0.0 255.255.0.0 network at both ends with a site to site vpn connection in the middle?
How would you expect traffic to know which part of the 10.10 network a client is going to be on? ie the local half of the network or the remote half of the network?

Unless you are bridging the vpn connection somehow (which I doubt), this is not going to work. You need different subnets so that you can route traffic accordingly based on destination addresses.
