Setting Up ExpressVPN Manually on DD-WRT Router

The manual configuration process of installing ExpressVPN on a DD-WRT router can be stressful, especially to a person with no knowledge of how to go about it. Fortunately, this guide will show you the configuration process. First, your DD-WRT router version has to be compatible with OpenVPN as it’s one of the most secure VPN protocols. It also needs to have at least 8MB of flash memory and 800MHz of CPU for basic VPN performance. Now, let’s dive into the configuration process.

1. Firstly, you have to get an ExpressVPN subscription if you don’t already have one. Go to the ExpressVPN website and click on the “Get ExpressVPN” bar.

Once the account creation process is complete, go to manual configuration settings by following this path: Set Up Other Devices > Manual Configuration.

2. Click the “OpenVPN” tab below the “Manual Configuration” section. Your service credentials (username and password) should be visible to you. Save your credentials somewhere or leave the browser window open because you will need them later in this guide. 

3. Just below your service credentials, you will see a list of servers based on their locations. Select a server you intend to use and download the OpenVPN configuration file (.ovpn) of that server. Depending on your choice, you can select TCP or UDP. Select UDP for a faster connection and TCP for a more reliable connection.
