How to configure VPN access on your iOS device

Jesus Vigo walks you through the steps of configuring your iOS device for VPN access.

 

VPN access on iOS
 

Virtual Private Network (VPN) was designed to allow remote access to enterprise users by extending a private network across a public network, such as those provided by the Internet.

Securing data traveling over public networks is achieved through the use of encrypted tunneling protocols. IPSec, PPTP, and L2TP are standards-compliant for use in IPv4 and IPv6 networks and are among the more commonly used protocols. Additionally, prior to establishing a tunnel through which data will be sent and received, end-points must authenticate through the use of passwords or pre-installed digital certificates.

Configure iOS for VPN access

Here are the requirements for configuring VPN access on your iOS device:

  • VPN Server or 3rd-party VPN service
  • VPN Account (provided by VPN administrator)
  • VPN Configuration settings (provided by VPN administrator)
  • End-point (iOS 4.1+ devices)
  • Wi-Fi or cellular Internet access

Follow these steps to configure iOS for VPN access:

  1. Go to Settings | General | VPN (Figure A)

  3. iOS supports three VPN protocols: L2TP (Figure C), PPTP, and IPSec. Though similar to configure, each has additional information that is required before a connection can be established.

  4. To configure IPSec, tap the IPSec tab and enter the credentials (Figure D), including configuration information provided by the VPN administrator or 3rd-party VPN service.

  7. If prompted with a connection message, tap OK to proceed. While optional, many VPN services provide a warning message with compliance information, referencing policies or other minutiae to inform end-users prior to establishing connectivity (Figure G).

  8. To verify the VPN service is active, a letters "VPN" will appear on the top-bar of all iOS devices to indicate all incoming/outgoing Internet traffic is being routed through the VPN service and is subject to the VPN service's guidelines (Figure H).

Giving users the ability to access data and corporate Intranet sites via VPN is both a secure and cost-effective way to maintain productivity while adhering to management and security policies. A side-benefit to VPN access for non-corporate users lies in how data is secured from outside probes. This is recommended by security experts in light of Wi-Fi hotspot use and the threat to private information they pose, because users often access personal information while they're connected.
