I want to connect to our company VPN.
I found guide on official Ubuntu documentation but that is not valid for Kubuntu or KDE desktop environment.
Is there alternative way to do this on Kubuntu or via terminal?
Connecting to PPTP VPN in Kubuntu 16.04 is easy. Follow the procedure:
Click on the Network Manager Icon on the Panel
If you can't find that icon, install
sudo apt-get install plasma-nm
and add the widget to the panel
In the Opened Pop-Up notification, click on the Settings Icon at the right side.
On the New Connection Editor window, Click on the Add button and select Point-to-Point Tunneling Protocol from the dropdown menu.
On the New Connection (vpn) window, provide the vpn address in the Gateway field, fill username and password and click OK to save. You can leave NT Domain field empty.
Now you can connect to the VPN from the Network Manager Widget.
From OPs feedback, it seems you need to click on Advanced tab in Create new connection window and enable the option for USE MPPE Encryption option to be enable to use with Windows VPN.
Check the screenshot below for that
