All of our VPS nodes have PPP support enabled. All you need to do is enable it on your VPS, which can be done using the below steps:
1) Login to the VPS control panel
2) Select your VPS from the Virtual Servers list (click on the blue Manage button)
3) Click on the Settings tab under Controls
4) Click on the dropdown icon below PPP and select On
You’re all done. PPP support will now be enabled. You can verify this by logging in to your VPS via SSH and executing /usr/sbin/pppd however; you must first ensure that the PPP packages are installed (yum install ppp on CentOS or apt-get install ppp on Ubuntu or Debian).
