    but i can't see tap0 interface and cannot ping any address at remote location.

    I tried this config file at Windows OpenVPN client and all works fine.

    Could anyone help me?

    Thx in advance.

    Hi.

    After you see the message "Initialization Sequence Completed", open a new terminal (do not close the current one or hit Ctrl+c as you will interrupt the connection), and type ifconfig.
    What is the output?

    Re: Open VPN Issue

    Hi,

    I have solved problem by myself.

    Solution was adding to /etc/network/interfaces
    Code:
    auto tap0
    iface tap0 inet dhcp
    and everytime when i try to connect, after
    Code:
    Mon Feb 15 16:28:44 2010 Initialization Sequence Completed
    I need to reload networking using

    Code:
    sudo /etc/init.d/networking restart
    (Note, that on Kubuntu I don't need to restart networking, but starting openvpn from console causes double crash of KDE)
