How to set up ExpressVPN on OpenWRT Router
Compared to native router firmware, alternative firmware can give users more flexibility and control. Additionally, it can make room for more features to help users route network traffic effectively. There are several alternative router firmware worldwide, and one such firmware is OpenWRT. It is a Linux-based open-source firmware used for embedded operating systems to route network traffic.
One of the best ways to protect your network and router from unwanted intrusions is to use a VPN. This article focuses on how you can set up and utilize one of the best VPN services on OpenWRT. Let’s dive in!

Setting Up ExpressVPN on OpenWRT Router
You can only set up ExpressVPN on any router with OpenWRT firmware manually. It is challenging to configure ExpressVPN manually on OpenWRT without any technical knowledge. However, this guide will take you through every step of the configuration process. So, you need to be careful and pay rapt attention to the steps we will show you below. You need to install LuCI (Graphical User Interface for OpenWRT) and have SSH access to your OpenWRT router.
1. Firstly, you need to open an account with ExpressVPN. Ignore this step if you already have an account with the VPN service provider. Head over to ExpressVPN’s homepage and click the “Get ExpressVPN” bar. Select a subscription plan, enter your email address, and choose your payment method on the resulting page. When you’re done creating your account, navigate to the manual configuration settings via this path: Set Up Other Devices > Manual Configuration.
2. Under the “Manual Configuration” part, click on the “OpenVPN” tab. Note your service username and password because you’ll need them later on. Now, leave the browser window open and move on to the next step.
3. Connect to your router using the SSH protocol. You can use the terminal application or Putty (using Windows OS). Note that you’ll need the IP address (default is usually 192.168.1.1) and password (default usually “admin”) of your router. You can check ExpressVPN’s website if you’re having issues finding your IP address. Enter the command below to connect to your router on a terminal application.
4. Enter the commands below to install the necessary packages needed for the rest of the configuration process.
opkg install -force-overwrite openvpn-openssl luci-app-openvpn
5. Now that you’ve installed the LuCI web interface, you can log in to your router’s admin panel using your password and username. You should see an OpenVPN menu by following this path: VPN > OpenVPN.
6. Next, enter the following commands on your router using ssh.
# Configure firewall
uci rename firewall.@zone=”lan”
uci rename firewall.@zone=”wan”
uci del_list firewall.wan.device=”tun+”
uci add_list firewall.wan.device=”tun+”
uci commit firewall
7. Afterward, create two folders at any location on your computer.
8. Next, create a file with the name “user.auth” in the “openvpn” folder. Put your ExpressVPN service username and password (check step 3) on the first and second lines, respectively. Save it and close the file.
9. Download the OpenVPN configuration files and save them to the “config” folder. In addition, download the zip file that has certificates and keys. Once downloaded, extract and store the files in the “openvpn” folder.
10. Check if the router has a /etc/openvpn folder (you can run the ls -l /etc command to check). If the folder is not on the router, you can use the mkdir /etc/openvpn to create it.
11. Then use the command below to copy the openvpn file on your computer to the folder in step 10 above.
scp openvpn/* root@OpenWrt:/etc/openvpn/
12. Also, change the names of the OpenVPN configuration files (.ovpn) to be at less than or equal to 20 characters (use only alphanumeric, hyphens, and underscores) and remove the “.ovpn” extension. This step helps in changing the OpenVPN configuration files to UCI configuration files.
13. Next, you need to use a text editor to edit certificates and keys out of the “.conf” files for every server location you intend to use. Afterward, the content of the files should look like the one below.
remote example-server.expressnetw.com 1195
verify-x509-name Server name-prefix
All the files are identical except for the URL in the 6th line above, which is different for each file.
14. The UCI config files should look like the config below, except for the filename and URL.
config openvpn ‘filename’ # Country
option enabled ‘1’
option client ‘1’
option proto ‘udp’
option dev ‘tun’
option fast_io ‘1’
option persist_key ‘1’
option persist_tun ‘1’
option nobind ‘1’
list remote ‘example-server.expressnetw.com’
option port ‘1195’
option remote_random ‘1’
option pull ‘1’
option comp_lzo ‘no’
option tls_client ‘1’
option verify_x509_name ‘Server name-prefix’
option ns_cert_type ‘server’
option route_method ‘exe’
option route_delay ‘2’
option tun_mtu ‘1500’
option fragment ‘1300’
option mssfix ‘1200’
option verb ‘3’
option cipher ‘AES-256-CBC’
option keysize ‘256’
option auth ‘SHA512’
option sndbuf ‘524288’
option rcvbuf ‘524288’
option ca ‘/etc/openvpn/ca2.crt’
option cert ‘/etc/openvpn/client.crt’
option key ‘/etc/openvpn/client.key’
option tls_auth ‘/etc/openvpn/ta.key’
option key_direction ‘1’
option auth_user_pass ‘/etc/openvpn/user.auth’
15. Then, you need to create a folder in the /overlay folder of the router for storing the OpenVPN configuration files (UCI files) of the server(s) you intend to use. In this guide we use /overlay/.ovpn.
16. Next, copy the UCI files to the router using the command below.
scp overlay/* root@OpenWrt:/overlay/.ovpn
You can replace the asterisk above with the filename of the configuration file.
17. Enter the commands below to select the VPN connection you intend to use.
cp /overlay/.ovpn/filename /etc/config/openvpn
You’ll have to do this each time you want to connect to a different server. Always remember to replace “filename” with the name of your config file.
18. Finally, go to the OpenVPN section on LuCI using this path: LuCI > VPN > OpenVPN. Then, enable the OpenVPN instance of the server you want to use. Afterward, select “Save & Apply.”
