VPN for iPad
VPNs for iPad work exactly the same as with any other iOS device. There are instructions on how to set it up below.
When choosing a VPN for your iPad, you will have a choice of PPTP or L2TP VPN. L2TP may come with a variety of encryption styles, but most often you'll see IPSec, so the style of VPN you download from the VPN service provider of your choice may be written as L2TP/IPSec. PPTP uses a simpler encryption style known as PPP, but is rarely written that way.
The main differences between PPTP and L2TP for iPad is going to be speed an security. If speed is a concern, for example if you are downloading, streaming TV, or are on a shoddy network, then PPTP is your VPN of choice. It's easier to install, lightweight, and requires less bandwidth to change your IP and connect to the VPN server.
L2TP is more secure because of the style of VPN tunneling (that's the L2TP part), and the encryption (L2TP has a range of 360-bit to 2048-bit encryption, this will depend on your service provider). But because of this extra encryption and beefed up security features, you may notice a slower connection.
Again, this will depend on a number of variables. Such variables include the quality of the VPN server you connect to, how many other users are on the same server, your distance from the server (closer is faster), and your original internet connection. This is why choosing a VPN service that allows for free server switching is a good idea. It allows you to experiment with different server connections without incurring switching fees.
Some VPN services have apps designed for iOS devices. These make setup much easier, regardless if you choose PPTP or L2TP. Here are some of my favorite services with iOS apps.

How to Configure your VPN
Go to Settings > General > Network > VPN > Add VPN Configuration. Then use the VPN settings for your device.
* Server = your computer's external IP or hostname.
* Account = your account login
* RSA SecurID = OFF
* Password = your account password
* Secret = computer's secret, chosen during set-up.
* Send all traffic = ON
Turn the VPN on or off
If you have created a VPN configuration, you can turn on/off the VPN in the Settings area. Remember, any device will drop the VPN connection when you change networks.
