Just a thought, did you try a tracert or monitoring the remote IP(s) on the ISA in question?

The actual connection VPN connection is working fine, the issue is they can't see anything beyond the ISA Server. So we connect via VPN and are allocated an IP address from the internal DHCP pool all this looks fine. I can now ping the ISA Server's internal IP address but I can't ping any devices beyond this. At present the VPN works perfectly for one of the IP's in the range allocated. I have checked this against other ISA Servers we have installed and everything looks fine. I have removed VPN and recreated it but still the same problem. Anyone able to shed any light on what might be the issue.
