What is the best free SSL VPN client that works on 64 and 32 bit windows clients?

When you say SSL VPN, do you mean a VPN that uses SSL or an SSL gateway that acts like a VPN? –  Magus May 6 '09 at 20:11
I'm really looking for something that I can use to replace the Forticlient SSL VPN software, but also want something that can be used to access other networks. I assume this is a VPN that uses SSL. –  Nick R May 6 '09 at 21:08
Yes. This is a VPN that uses SSL to negotiate the connection securely. –  Magus May 7 '09 at 14:38

Try OpenVPN (http://openvpn.net/). It's cross-platform, completely free, extremely secure, and once configured it's extremely easy to deploy. I can't confirm whether it specifically targets x64, but the x86 build should work on the x64 architecture.

Edit: I should mention that OpenVPN won a "Bossie" in 2007 as the best Open Source VPN.

Also, OpenVPN 2.1 is Vista-ready on both x86 and x64.

+1 Openvpn is quality, free, and open source –  Chris Ballance Apr 30 '09 at 21:23
+1 openvpn - used it for year and found it very robust and far easier to manage than ipsec –  John McC Apr 30 '09 at 21:58
OpenVPN (openvpn.net) is only able to connect to their own service - which they call "Shield Exchange". –  Ian Boyd Jul 21 '11 at 20:55

You could use Windows 2008 Server and the built-in Secure Socket Tunneling Protocol? You could use the built-in Windows Vista/7 networking client and the configuration is very simple.

Just re-read the question and missed the "free" requirement. Sorry about that... –  Dscoduc Jan 21 '10 at 17:05
