Setup Namecheap VPN on DD-WRT v3 Router

The following is required for Namecheap VPN to work with a DD-WRT v3 router:
  • A secure Namecheap VPN connection (Don’t have one? Sign up for VPN service).
  • An internet connection
  • DD-WRT compatible router running v3
Before following this guide, you will need to install DD-WRT on your router. To do this, you will need to go to DD-WRT router database and search for your router model number to see if your router is compatible or find a beta build for your router. This guide uses KONG's beta build of DD-WRT v3.0-r31520M on a Netgear R7000.

IMPORTANT NOTE: Certain beta builds may not work with OpenVPN. Please read the feedback in the build forum before installing a beta build. Also note, regardless of what model router you have or version of DD-WRT you are installing, there is a chance of bricking your router (i.e. rendering the router completely useless) if the process of putting DD-WRT on the router does not complete properly. Please thoroughly read and follow the related documentation regarding the updating procedure for you router, to minimize the risk of bricking your router.

Initial DD-WRT Setup and Important Notes

1. Please check and consider the following before setting up your VPN connection in DD-WRT:

  • If you are running a router-behind-router configuration you will want to make sure your DD-WRT router is on a different subnet than any other router/modem on your network. This can be done by going to Setup/Basic Setup tab and changing your Local IP address to "" without quotes.
  • We suggest adding the following static DNS addresses: and, on the basic setup tab.
  • Please check to ensure the NTP client is enabled and set to the correct time zone, which can be found at the bottom of the basic setup tab.

2. Enable Syslogd so you can get logs if you run into any trouble with your DD-WRT v3 VPN  router setup. You can do this by going to Services tab and scrolling down to System Log, then enable Syslogd.


Configuring the VPN Connection
