Connecting to a Virtual Private
Network (VPN)
From your device, you can add, set up, and manage
virtual private networks (VPNs) that allow you to
connect and access resources inside a secured local
network, such as your corporate network.
Preparing Your Device for VPN Connection
Depending on the type of VPN you are using at work,
you may be required to enter your login credentials or
install security certificates before you can connect to
your company’s local network. You can get this
information from your network administrator.
Also, your device must first establish a Wi-Fi or data
connection before you can initiate a VPN connection.
For information about setting up and using these
connections on your device, see “Launching a Web
Connection” and “Turning Wi-Fi On and Connecting to
a Wireless Network.”
