    Re: VPN Problem

    Ok I found the solution and it worked.I hope this helps others too.I have to run in terminal: sudo modprobe nf_conntrack_pptp In order not to run this command everytime:

    Open your terminal and type as
    gedit /etc/rc.local
    Then add following line at ending
    nohup sudo modprobe nf_conntrack_pptp
    Then save and close your file.
    Restart your Ubuntu and check.
