How to connect to your corporate office
using a VPN
What is a VPN, and do I need to change my router settings? A VPN (Virtual
Private Network) is a network that uses a public network, such as the Internet,
to provide secure communications between a remote computer and another
network. Corporations often provide VPN access to their networks to enable
employees to work from remote offices or while traveling. Most corporate VPNs
use the Internet to provide connectivity between remote employees and the
corporate network.
For a typical VPN, the corporation installs a VPN gateway on their corporate
network. Employees authorized to work remotely connect to the VPN gateway
through the Internet using VPN software and security methods provided by
their employers. Robust security and authentication schemes ensure a secure
connection and access by only authorized users.
The default VPN settings in your router have been configured to pass through
(allow) the most common types of VPN protocols, so usually no changes are
needed.
To change your VPN passthrough settings:

Log into the browser-based utility (see “How to open the browser-based
utility” on page 14).
