How to set up PPTP VPN on DD-WRT Routers

In this tutorial we will show you how to set up PPTP VPN on DD-WRT Routers but first let’s see what are our requirements and recommendations.

Requirements

In order to set up the PPTP VPN you will need:

  1. A CactusVPN account. If you don’t have one you can try our services for free.
  2. Your VPN username, password and VPN server address. You can find them in your account on our website, by going to Settings.

Recommendations

PPTP is not the best option for online security and privacy. We recommend using OpenVPN.

If you still want to set up PPTP VPN manually, go step-by-step through following instructions:

Setup Preparations

In order to set up PPTP VPN on DD-WRT routers you have to flash your router with DD-WRT firmware and set router local IP address as 192.168.1.1.

Also please, check if you can connect to Internet via Wi-Fi from DD-WRT router.

We also recommend checking VPN on your PC/Mac to ensure that your network configuration and ISP allow PPTP VPN connections.

Connect to your router. For that you have to put in your browser the following address: http://192.168.1.1

If this doesn’t work, please consult your router’s manual to find what is the Default Gateway Address.

Also you have to set your network connection to obtain IP address automatically if you connect to your router via Ethernet.

Setup Instructions

There are two different ways to set up PPTP VPN on a DD-WRT router. Please choose if you want to set up PPTP using a script or without using a script.

  1. Go to Setup tab and then select Basic Setup (1).

    Select PPTP from the Connection Type drop down menu (2).

    In the Gateway (PPTP server) field (3) type the IP address of the CactusVPN server you want to connect to.

    You can find all the available VPN servers in your account on our website, by going to Settings -> VPN Servers.

    In the Username (4) and Passwords (5) fields enter your VPN username and password.

    Set MPPE Encryption (7) and Packet Reordering (8) to Enabled.

    On some versions of DD-WRT there is also PPTP encryption, set it as well to Enabled.

    In the Optional Settings zone change MTU to Manual (11) and type the value 1460 (12) in the field and set STP as Disabled (13).

    In the Network setup field enter the IP address for the DD-WRT access point (14).

    Important!If this is the second router then you must set a different Local IP address then your main router.
