Configure Tomato Router Firmware for Namecheap VPN OpenVPN

This tutorial will walk you through configuring Namecheap VPN OpenVPN in Tomato firmware and will allow you to establish a permanent VPN tunnel from your router. This guide was prepared and based on a Namecheap OpenVPN installation on a Netgear Nighthawk 7000 router that has been flashed with Tomato OpenVPN firmware.

Before getting started

The following are required to configure Namecheap OpenVPN on Tomato firmware:
  • An Namecheap VPN account (Don't have one? Sign up here)
  • An internet connection
  • Tomato flashed router

IMPORTANT NOTE: Regardless of what model router you have or the version of Tomato firmware you are installing, there is a small chance of bricking your router (i.e., rendering the router completely useless) if the process of putting Tomato on the router does not complete properly. Please thoroughly read and follow the related documentation regarding the updating procedure for your router.

1. Log in to the router control panel by entering the router’s default IP address 192.168.1.1 to the address bar of your preferred browser (if you changed your routerdefault IP address, enter that into your browser instead). While connecting using 192.168.1.1, the URL may change to http://192.168.1.1.


2. You will be redirected to the user interface of the router; select VPN listed under Status Overview on the menu on the left:
