How to Add VPN to DD-WRT

Enable VPN to access private network resources via the Internet when you are on traveling.

Add PPTP or Point-to-Point Tunneling Protocol configuration to your DD-WRT router using the Web administration pages when remote access to your private network is required. DD-WRT includes a PPTP service, but it is disabled by default and requires configuration before VPN clients can access the private network. Enable the DD-WRT PPTP service to provide secure, encrypted access to your private network.

Things You'll Need

• Router with DD-WRT installed
• PC running Windows 7

Instructions

1. Click the Windows “Start” button and type “cmd” into the search box. Right-click on the “Command Line” icon in the search results and select “Run as Administrator” from the context menu.

2. Type “ipconfig /all” on the command line. Note the Gateway IP address and the Local Area Connection IP address displayed in the command line output.

3. Click the Windows “Start” button and then click “Internet Explorer.” Click once in the address bar at the top of the Internet Explorer window.

4. Type the Gateway IP address noted in Step 2 and press “Enter.” Type the the DD-WRT router administrator's username in the “User Name” box when prompted. Type the account password into the “Password” box and press “Enter.”

5. Click the “Services” tab, then click “VPN.” Click the “Enable” radio button under “PPTP Server.” Click the “Apply Settings” button.

6. Find the IP address listed next to “WAN IP” in the upper right corner of the Web page. Type the WAN IP address into the Server IP field.

7. Type private network IP addresses you want to use for VPN clients into the “Client IP(s)” text box. For example, if the IP address for the Windows 7 computer noted earlier is 192.168.1.3 and you want 10 client IP addresses dedicated to the VPN, type “192.168.1.201-210” into the “Client IP(s)” text box.

8. Type a username and password you want to use for VPN authentication into the “CHAP-Secrets” text box. Use the format “fred * fredspass *” but replace “fred” with a username you want to use and replace “fredspass” with a password you want to use. Note that the password must be entered between asterisks as shown in the example. Press “Enter” and type another VPN client username and password. Repeat this step until all usernames and passwords for the VPN have been entered.

9. Click the “Apply Settings” button.
