Been wanting to do some testing on VPN connectivity and SoftEther (a multi-protocol open source VPN program) came up.

Here are some benefits of SoftEther as mentioned on their web site:

SoftEther VPN is an optimum alternative to OpenVPN and Microsoft’s VPN servers. SoftEther VPN has a clone-function of OpenVPN Server. You can integrate from OpenVPN to SoftEther VPN smoothly. SoftEther VPN is faster than OpenVPN. SoftEther VPN also supports Microsoft SSTP VPN for Windows Vista / 7 / 8. No more need to pay expensive charges for Windows Server license for Remote-Access VPN function.

Still looking for a place to work on these projects again.  Any one with any experience using SoftEther, please let us know how things are going with your projects.
