Folks,
I can connect using the new VPN client on my 7K 64 machine but for some reason the packets are not encrypted. When I use the XP machine with the same credentials everything works great, any ideas?
Thanks,

Hi,
can you clarify what you mean by "not encrypted". Does the vpn server show the SAs being established?
Thanks

Hi,
I'm having the same issue: on my Windows 7 64bit with VPN Client 5.0.07.0290 the VPN comes up, but no data is going over the connection. Also I have no encrypted/decrypted packets, but all of them are discarded. Did you find the solution?
Greets,

First try this:
On a Windows 7 PC go to C:\Program Files\Cisco Systems\VPN Client\Profiles
Open
add these commands at the end:
ForceNatT=1
UseIKELegacyPort=1
Test the VPN client!
If it still has issues,try reinstalling the VPN client after DNE upgrade via:

If you are using WWAN card try this:
As the VPN Client on Windows 7 does not support WWAN devices
The current releases of VPN client software use an NDIS (Network Driver Interface Specification) intermediate driver that is based on NDIS 5.0 (specifications developed for Windows Vista and XP).
However, the native Windows 7 Mobile Broadband and Some Wireless WWAN miniport drivers are based on NDIS 6.2 specifications. VPN client applications using intermediate drivers based on NDIS 5.x specifications have compatibility issues with drivers compliant with Windows 7 Mobile Broadband.
Some vendors for wireless cards provides WWAN miniport drivers for Windows 7 that are Windows 7 logo certified and based on NDIS 6.2 (specifications for WWAN interfaces that can be supported natively in Windows 7).
The Cisco VPN client along with some other third party clients has compatibility issues with NDIS 6.2 WWAN miniport drivers:
The Cisco VPN client release notes state “The VPN Client on Windows 7 does not support WWAN devices (also called wireless data cards)”:
There is a workaround provided by some WWAN vendors,
Either we can downgrade the NDIS divers or we can setup Dial up connection for the internet, which is not affected by this problem.

I tested it and it works.
