I'm experiencing an issue with the IPSEC VPN Client (5.0.06.0110) on Windows 7 with a 3G internet connection. I'm able to connect and the virtual adapter retrieves an IP Address, however, I cannot ping any of the resources behind the PIX. I can disable the 3G connection and use a traditional wireless connection without issue.
Any idea what might be causing the problem when using the 3G connection? Perhaps the provider is blocking ISAKMP or ESP? NAT-Traversal is enabled. I'm stumped.
