Fortunately, you can use NordVPN with your Asus router. These instructions will help you set up an OpenVPN connection with NordVPN on your ASUS router flashed with AsusWRT-Merlin firmware. The instructions were made using an ASUS RT-AC87U router with version 384.19 of the AsusWRT-Merlin firmware.
- Log in to the control panel of your router. To do this, open your internet browser and in the address bar enter the router’s address, which is 192.168.1.1 by default. A prompt will appear, asking you to enter your username and password. If you have never changed the username or password, enter the default values admin for the username and admin for the password.
- Once you have signed in, select VPN in the left sidebar.
- In the VPN section, go to the OpenVPN Clients tab.
- Now you need to download the OpenVPN configuration files.
Follow the steps below to find the best server for your connection:
-
Log into your Nord Account, and click NordVPN.
- Scroll down to Advanced Settings and click Set up NordVPN manually.
- Select the Server recommendation tab. According to your location, the best server will be recommended.
-
By pressing Advanced filters you can further customize the recommended servers by selecting the Server type and the Security protocol.
In case you wish to select a specific server, follow these steps:
- Under Set up NordVPN manually, select OpenVPN configuration files.
- Find the server you wish to connect to by using the Search bar or by scrolling down and download it by clicking Download UDP or Download TCP.
- Go back to the router’s control panel and click Choose File….
- Select the configuration file you have just downloaded and press Open. If you need help deciding which configuration file to choose, feel free to contact our customer support team.
We recommend using UDP files that have udp1194 in their names. It means that the configuration will use UDP, which is faster than TCP.
- Click Upload and wait for the page to refresh.
- Once the page has refreshed, most fields will be filled in automatically, except for your NordVPN service username and password — you will have to type those in manually.
Follow the steps below to find the service credentials for manual connection setup:
-
Log into your Nord Account, click NordVPN, and, under Manual setup, click on Service credentials. Here you'll find the Username and Password needed to connect manually.
- Set Accept DNS Configuration to Strict if you are planning to use NordVPN on all your home network devices or Exclusive if you will use it on specific devices. We recommend setting it to Strict.
- In the Custom Configuration field, enter this text:
remote-cert-tls server
remote-random
nobind
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
persist-key
persist-tun
ping-timer-rem
reneg-sec 0
#log /tmp/vpn.log
- Now you need to configure NordVPN’s DNS settings. In the left sidebar, click WAN. In the Connect to DNS Server automatically field, select No and fill in NordVPN’s DNS servers as follows:
103.86.96.100
103.86.99.100
- Click Apply at the bottom of the page and wait a few seconds for the changes to apply. If you can see the green ON button, congratulations – you are now connected! You can verify this by going back to the VPN Status tab or by checking your IP address on our website (you will find your connection status, along with your IP address and ISP, at the top of the page).
Optional Kill Switch setup (for advanced users):
Here’s how to set up the Kill Switch feature on AsusWRT Merlin firmware:
- Go to VPN > OpenVPN Client.
- Under Advanced Settings, select Redirect Internet Traffic: Policy Rules
- A new option will appear, Block routed clients if tunnel goes down. Enable it.
- Under Rules for routing client traffic through the tunnel, add your whole network:
Description: all devices
Source IP: 192.168.1.0/24 (if you have a different network or subnet mask, change accordingly)
Destination IP: leave blank
Iface: VP
