  22 # Hi folks! I hope this code is useful for all. I needed something to handle  #
  23 # my VPN Connections in a comfortable way. As a prerequisite i needed             #
  24 # something that makes sure the vpn roadwarrior are able to have a fixed          #
  25 # ip-address. So i developed the ccd extension for the vpn server.                        #
  26 #                                                                                                                                                         #
  27 # Now that the ccd extension is ready i am able to develop the main request.  #
  28 # Any feedback is appreciated.                                                                                            #
