VPN not able to connect to DMZ network

Asked by taski303 in Virtual Private Networking (VPN), Cisco PIX Firewall

Tags: Cisco, ASA 5500, 5540 and 5505, VPN premium

I have a site to site VPN from Denver to Tokyo.  We can see that the VPN tunnel is running but unable to access the DMZ.  The firewall doesn't even seem to route to the DMZ but we are able to access the internal IP address interface in Tokyo.  Posted below are the configurations with several security items replaced with X.  Any idea's?
