I am unable to connect to a Sonicwall TZ 100 via Sonicwall Global VPN client. I know the site is up and working because everyone else connects with no problems. I know licensing is not an issue.  I know I have the proper group key.
I uninstalled - ran the Sonicwall cleanup util and still had problems. Loaded on another VM and still had the issue.
Failed to find MAC address 00:60:73:xx:xx:xx  in the system interfaces table
Starting ISAKMP Phase 1 negotiation
The Peer is Not Responding to Phase 1 ISAKMP Requests
An error has occurred

Here is my setup:
Windows 7 ultimate host with Cisco CPN client installed
Security: AVG Internet Security 9.0
Windows XP SP3 VM with Sonicwall GVPN client ( installed.
Security : Microsoft Security Essentials - standard firewall
My side: Behind a Cisco 851 Firewall router with no outbound blocking (that I am aware of) - business cable modem
Their side: Only the Sonicwall on a T1 line.
Only running Global VPN from a VM and never when the Cisco  VPN client is running.

Some Internet research suggests that the Cisco may be blocking outgoing ISAKMP packets.  I am the only one trying from behind anything Cisco so no help.
