Cannot connect mac to proprietary Softether Server

[Mr.G]

Greetings.

I know that on a mac you should enable the L2TP or PPTP protocol to allow for "easy" access to the VPN server, but I'm working at a company that does not allow any of these protocols. This means that I am stuck with the Softether VPN server, from a macbook without a GUI application to connect to the server.

The below info is fake, just to help with exemplify.
Server: vpn.company.com
Port: 443
User: andersuser
Pw: thepassword

How do I use the command line commands to connect to the server? I have downloaded the command line commands and I have compiled them with "make". I have also run tests.

Again - the server ONLY uses proprietary encryption. L2TP, PPTP or anything else is not available and I am not admin so I cannot fix that.

Please help? Step by step would be awesome.

Okie, I can stumble a bit into the setup process, but I'm not there yet.

After compiling programs:

sudo ./vpnclient start
OK

sudo ./vpncmd localhost /CLIENT
Vpncmd command - SoftEther VPN Command Line Management Utility

Connected to VPN Client "localhost".

VPN Client>niccreate
NicCreate command - Create New Virtual Network Adapter
Virtual Network Adapter Name: VPN

Error occurred. (Error code: 31)
Installation of the Virtual Network Adapter device driver failed.
VPN Client>

Niclist shows me zero Virtual Adapters. I create one and get an Error Code: 31. What am I doing wrong?
I am root as you can see, since i started the process with sudo

How about using OpenVPN?
