As others pointed out the best way would be to install sstp-client but iSSTP can also work, however note the following:
- You need to ensure you get the latest version (1.0.15 currently) as 1.0.14 has a bug and does not work.
- If you use iSSTP ensure you replace their bundled sstpc file (Contents/Resources) with the latest from where you installed it (/usr/local/Cellar/sstp-client/1.0.15/sbin)
brew install sstp-client
sudo /usr/local/Cellar/sstp-client/1.0.15/sbin/sstpc --password *** --user *** <host>
For PAP I use the following command:
sudo /usr/local/Cellar/sstp-client/1.0.15/sbin/sstpc --password *** --user *** <host> noauth defaultroute require-pap
In iSSTP (once you replace their old binary) ensure you set the pptp options in advanced (see here: https://linux.die.net/man/8/pppd)
