VPNs (virtual private networks) are often used within organizations to allow you to communicate private information securely over a non-private network. You may need to configure VPN, for example, to access your work email on iPhone or iPod touch.
iPhone or iPod touch devices with iPhone 2.0 software or later can connect to VPNs that use the L2TP, PPTP or Cisco IPSec VPN protocols. VPN works over both Wi-Fi and cellular data network connections.
iPhone or iPod touch devices with iPhone OS 3.0 or later can utilize VPN Proxy configurations. VPN On Demand is also an option with iPhone OS 3.0 and can be configured via profiles created with the iPhone Configuration Utility. For more information regarding VPN Proxy or VPN On Demand, see the
iPhone OS Enterprise Deployment Guide for iPhone Software 3.0

Choose General > Network > VPN and then choose Add VPN Configuration. Ask your network administrator which settings to use. In most cases, if you've set up a similar VPN on your computer, you can use the same VPN settings for iPhone or iPod touch.*
Turn VPN on or off
Once you've created a VPN configuration, the VPN switch at the top of the VPN Configurations list can be used to turn VPN on or off.
Choose your desired VPN configuration and tap or slide the switch to turn VPN on or off.
If you see a message that says Shared Secret is missing, check with your network administrator for assistance. See document HT1288, "iPhone and iPod touch: Supported protocols for VPN" for additional information.
