Unable to ping or transfer traffic to VPN clients from my ISA protected network to our Cisco ASA

I terminate my VPN connection at the Cisco ASA and I can ping and communicate from the ASA to remote VPN client.  However I cannot get the ISA Server to pass any traffic to or from the VPN clients.  I have tried putting rules in the ISA to allow conmication, but everything is getting denied.  The network template I am using is for a back-end firewall.
Here is a rough example of our layout:
Internet----Router----Cisco ASA----ISA Server 2006----Private LAN

    You could jst terminate the VPN clients on the ISA server, rather than the ASA.

    Keeps the deign the same and you just need to allow the VPN traffic through the ASA to the ISA.
