So, we've been facing some "opposition" at work to moving to an x64 environment in general. People love the idea of more RAM to playwith, etc. but a lot of them are still stuck using certain tools.

One of these tools is the Cisco IPSec VPN Client. This client is 32-bit only, and will never be ported to x64. Cisco's current claim is that if you want x64 VPN connections, you need to use SSL or DTLS with their new AnyConnect client. Anyconnect is great, and it works well, but each ASA we have is licensed for only 2 SSL connections, but we have licenses for over 20 IPSec connections. With that in mind I've been researching the options for x64 VPN clients. Didn't find much until recently I cam across Shrewsoft's VPN client. It's an open source client, is compatible with all versions of Windows, and seems to support everything we'll be needing.

I don't know if it will work, or how well it will work, etc. I will find out when I start testing tonight. But considering that IPSec VPN connections are prevalent, I figured I would share what I found with all of you.
