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

Log into the browser-based utility (see “How to open the browser-based

utility” on page 21).

Click the Security tab, then click the VPN Passthrough page.

Select each setting that you want to change.

TIP

For brief descriptions of the VPN passthrough field settings, click

Help in the right side of the screen. More complete descriptions are

provided below.

• IPSec Passthrough – IPSec (Internet Protocol Security) is a suite of

protocols used to implement secure exchange of packets at the IP

layer. The VPN clients on the local network can establish an IPSec VPN

tunnel through the router. This option is enabled by default.

• PPTP Passthrough – PPTP (Point-to-Point Tunneling Protocol) allows

the PPP (Point-to-Point Protocol) to be tunneled through an IP network.

The VPN clients on the local network can establish a PPTP VPN tunnel

through the router. This option is enabled by default.

• L2TP Passthrough – L2TP (Layer 2 Tunneling Protocol) enables point-

to-point sessions using the Internet on the Layer 2 level. The VPN

clients on the local network can establish an L2TP VPN tunnel through

the router. This option is enabled by default.

How to optimize your router for gaming

and voice

How does my router prioritize traffic to the Internet? Your router has QoS

(Quality of Service) settings that can prioritize traffic from your network out to

the Internet. Performance for demanding, real-time applications, such as online

gaming, VoIP calls, video streaming, and videoconferencing, can be improved

by configuring Internet access priorities.

QoS is applied only to traffic that is uploaded to the Internet. The router cannot

control the quality of the traffic after it reaches the Internet.

TIP

For more information on optimizing your router for online gaming,

see “Port Forwarding and Port Triggering” on page 50.
