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:
Security > VPN Passthrough

utility” on page 14)°

Click the
