I'm in the process of replacing a ForeFront TMG 2010 firewall with a SonicWall NSA 3600; the current firewall provides VPN access to our network using SSTP, and it works like a charm with any recent Windows client, without requiring the installation of any additional software.
The SonicWall firewall supports SSL VPNs, but it apparently requires a software called NetExtender to be installed; it can be downloaded directly from the firewall login page, thus it's not really a big deal... but we would really prefer to avoid installing any software and use only the Windows built-in VPN client.
Is it possible to estblish a SSL VPN connection to a SonicWall firewall from a Windows computer using only the built-in VPN client? If yes, how?
N.B. The firewall also supports L2TP ant it works fine with the Windows built-in VPN client (and several other ones); unfortunately, this is not an option: our people often travel to customer sites were Internet access is restricted to HTTP/S, thus a SSL VPN is a must.
