Can't connect to VPN [pptp]

[PungPillaren]

Hello!

I'm trying to setup VPN on my Kubuntu 14.04 but it doesn't seem to be working.
I've already set it up on my android phone without problem.

I'm trying to set i up with the default connection manager (connection manager -> add -> pptp) using default settings + mppe
I'm 100% sure the gateway, usename, and password is correct (as i can connect with my phone).

In the notification manager I get:

Active connection state changed
Missing VPN plugin
VPN connection state changed
Device failed to activate

In the syslog I get:

Some guide told me to "sudo modprobe ppp_mppe" but it did nothing.
I also did "sudo apt-get install pptp-linux" but it was already the latest version.


There seems to be a lot of warnings about some VPN plugin.
Is there something I need to install to get VPN to work?

The synchronous pptp option is NOT activated

Turns out, I can only connect 1 device at the time. When I disconnected my phone I could connect with linux.
My VPN said I could use 3 connections but it doesn't seem to active yet.

Do you only have the option of PPTP? I wrote a tutorial for the OpenVPN way a few weeks ago:

No I actually found the certs for openvpn after some digging.
So now I can run openvpn on my desktop and pptp on my phone.

Nice

There's also a GPL application for Android called "OpenVPN for Android" you could use if you wanted to use OpenVPN there too.
