Auto reboot if no ping response

  • Hi all,

    I would like to implement a keep alive mechanism on a PPP (3G) connection .  The problem we have is the GSM carrier sometimes drops the connection after a few hours and we have to manually re-dial.  Is there an easy way I could implement the following feature:

    Ping WAN IP address i.e. every 30 seconds
    If there is no reply after 3 attempts then consider the connection as DOWN
    Reboot pfSense box
    PPP connection is then re-established on startup.

    Any help would be much appreciated.

    Thank you  :)
