I installed an Ubuntu 8.10 VMWare appliance at home on my Mac Pro and needed to connect to work. I wanted my VM to connect rather than OS X so I looked for a VPN client. Cisco didn't permit me to use their client so I found the one I'm using now at the URL above. My VMWare appliance is 32-bit so I tried installing an older, 32-bit Cisco client from that site, couldn't make it work, installed a bunch of patches, etc. Finally, I just tried installing the latest 64-bit version and it worked! I'm very pleased. Time to stay up even later working.
Thanks, not-Cisco!
