Below is deprecated! But I can learn something.

Download sourcenya di: https://sourceforge.net/projects/sstp-client/files/sstp-client/

sudo make install

sudo sstpc <IP_ADDRESS> --user <USERNAME> --password <PASSWORD> --log-level 0 --cert-warn --tls-ext --uuid <UNIQUE_ID/DOMAINNAME> --save-server-route

Check connection using ifconfig, interfacename will be like ppp0

sudo route add default gw <IP_GATEWAY>
