This morning I finally got this to work after talking with Cisco support. They ran some tests against my IP address and discovered that access was block to key ports. They suggested I talk with my ISP. Before doing that I check my router configuration and noted that Firewall > Basic Settings > Block WAN Request: was set to Enable. I switch this to Disable and was then finally able to establish a VPN tunnel with QuickVPN version 22.214.171.124 under Vista Ultimate.
