I have discovered the Cisco software will not work with 64-bit Vista, and after fiddling around for a few hours, I found Vista has it's own built in. I cannot get it to work however, and am stuck. Have installed ShrewSoft VPN also but the settings are complicated - I have no idea how the few things I transfer into the Cisco client translate into the ShrewSoft client.
Any help with either of these would be muchly appreciated.
