The iPad's VPN Settings
After you tap Network on the General settings screen of your iPad, you see two controls: Wi-Fi and VPN. Here are the VPN settings. A virtual private network, or VPN, is a way for you to securely access your company’s network behind the firewall — using an encrypted Internet connection that acts as a secure tunnel for data.
You can configure a VPN on the iPad by following these steps:
Tap Settings→General→Network→VPN→Add VPN Configuration.
Tap one of the protocol options.
The iPad software supports the protocols L2TP (Layer 2 Tunneling Protocol), PPTP (Point-to-Point Tunneling Protocol), and Cisco IPsec, which apparently provides the kind of security that satisfies network administrators.
Using configuration settings provided by your company, fill in the appropriate server information, account, password, and other information.
Choose whether to turn on RSA SecurID authentication.
Better yet, lend your iPad to the techies where you work and let them fill in the blanks on your behalf.
After you configure your iPad for VPN usage, you can turn that capability on or off by tapping the VPN On or Off switch inside Settings.
