Thank's Peter, may be I was not specify in off, but we're traying to use
VB.NET for opening a VPN and after the tunnel is open then transmit and recive data using the app, by this time we manualy open the VPN and then transmit/recive data with the app, because it's take time and my users are'nt very familiar with pockets, we´re traying to do it simple and easy for end user. So we're looking the way do a VPN "dial-up" internally as you respond.
Thanks
Carlos
