Hi Kevin,

I would first check to see if Phase2 security associations are being
setup properly.  Even though Phase2 negotiations complete and "Tunnel
enabled" appears in the Shrew Connect dialog, it is possible that that
SAs are failing.  You can see the SA status using the VPN Trace utility
on the Security Associations tab. This page provides steps to start
logging using the Trace utility (remember to right-click and Run As
Administrator in Vista/Win7):

What you should see are two "MATURE" SAs setup shortly after you
initiate traffic (for instance ping) toward the remote network.

If you see them repeatedly going into LARVAL state, it means that
something isn't quite matched up with your Shrew policy and the gateway
