Overview

Virtual Private Networking (VPN) enables device connecting private networks or servers over internet/public networks. Layer Two Tunneling Protocol (L2TP)/IP Security Protocol (IPSec) and Point-to-Point Tunneling Protocol (PPTP) provide communications services and networking capabilities available in WinCE.

By default in Toardex WinCE Image does not include catalog item for establishing VPN communication services(L2TP/IPsec or PPTP).

Prerequisite

  1. Platform builder(WinCE 6.0 or WEC 7.0 depends which image you are working on).
  2. Toradex WinCE platform builder Workspace and BSP.

Note: We have not tested VPN on CE5.0, WEC2013 but it should work same way.

Catalog item to enable VPN communication services

  1. SYSGEN_PPP :- When this variable is set, the Dial-up Networking (RAS/PPP) Catalog item is included in the OS design.
  2. SYSGEN_L2TP :- When this variable is set, the L2TP/IPSec Catalog item is included in the OS design.
  3. SYSGEN_CERTS :- When this variable is set, the Certificates (CryptoAPI 2.0) Catalog item is included in the OS design.
  4. SYSGEN_CRYPTO_DSSDH :- When this variable is set, the Diffie-Hellman/DSS Provider Catalog item is included in the OS design.

Steps

  • Add above mentioned item in catalog Item View, then run Sysgen command in visual studio 2008(Build -> Advance Build Command ->Sysgen(blddemo -q). It will take some time depending upon your PC speed.
  • After Build succeeded, update your image with created image.
  • Navigate to Control Panel->Network and Dial-up Connections -> Make new Connection. Now VPN communication features should be available.

  • Configure VPN according to your server PSK(pre-shared key), server IP, username and password.
  • A new connection will be available in Network and Dial-up Connections for VPN connection.
