From my previous posts about 64-bit vpn clients there is a good addition to the list of options outside of Cisco for Windows 7 64-bit OS and that is Shrew Soft who just released an update to their client which supports Windows 7. The best part is the fact you can import Cisco PCF files. I've had good success when using it will Cisco ASA and PIX vpn configurations and some mixed results with Cisco VPN 3000 concentrator.
The current version is 2.1.5 but the 2.1.4 release worked on my Windows 7 64-bit client also. I have several clients also using it and they have not had any issues either. Hats off to the folks at Shrew Soft - appreciate having a working 64-bit IPsec client that is easy to use for Windows 7.
