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

1.Log into the browser-based utility (see “How to open the browser-based utility” on page 21).

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

3.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.

Setting Up: Advanced

••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.

4.Click Save Settings to save your changes.

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.
