DD-WRT Configuration VPN server

Before setting up the VPN Server, you must first make sure your installed build of DD-WRT includes the PPTP VPN features. The DD-WRT feature list shows this as “PPTP / PPTP Client” on their chart. Check the installed version on your router (which you can see in the upper right corner on the configuration pages) against the chart. If the feature is not included in your build, you will need to flash your router with a DD-WRT version which does include the “PPTP / PPTP Client”.

To turn on the PPTP VPN Server, navigate to the Services tab and then the VPN sub-tab and select the option to enable the PPTP Server.

Once enabled, several previously hidden options will appear. Configure them as follows:

• Server IP: Public IP address of the router
• Client IP(s): List of local IP’s (respective to the VPN network) to use when assigning IP addresses to clients connecting through the VPN. In our example, we are setting aside 5 IP addresses (192.168.16.5, .6, .7, .8, .9) for use by the VPN clients.
• CHAP-Secrets: User name and passwords for VPN authentication. The format is “user * password *” (user[space]*[space]password[space]*), with each entry on its own line. In our example, there is just a single accepted user name (jfaulkner) and password (SecretPassword1).

You can view detailed documentation on all of these options by clicking the “Help more…” link on this page on the right side of the DD-WRT configuration.

Once you are finished, click the Apply Settings button to push the configuration through to your DD-WRT router and you are finished.
