Please, tell me about what version of Cisco VPN can I run under Vista U x64 ?
Q: Does Cisco provide a VPN Client for Windows Vista?
A: At the time of writing (June 2007) Version 5 of the VPN Client is available for 32-bit Windows Vista. Support for 64-bit Windows Vista is not available at this time.
TIP: The Cisco AnyConnect VPN Client is now available for the Windows Operating Systems, which includes Vista 32 and 64-bit. The AnyConnect client supports SSL and DTLS. It does not support IPSec at this time. Additionally, AnyConnect is available only for use with a Cisco Adaptive Security Appliance that runs version 8.0(2) or later. The client can also be used in weblaunch mode with IOS appliances running version 12.4(15)T. VPN 3000 is not supported.
