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 14). 2. Click the Security tab, then click the VPN Passthrough page. 3. Select each setting that you want to change.

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 pointto-point sessions using the Internet on the Layer 2 level.
