It’s very simple. All you need is your interface private key. If you have any linux machine, use that or jnstall a vm if you don’t have one. Get their official linux app installed. Install wireguard too. Connect to nordvpn with command:
nordvpn c
After successful connection run
ifconfig nordlynx
write down its IP address somewhere, you’ll need it later.
sudo wg show nordlynx private-key
Output of this command should be something like this:
CKMAE9LARlt2eZHgGnNaSUYiKLLkJN7f3hed/bWm5E8=
This is your private key. Write it down. The key above is just a random key for demo purposes.
Now make sure you have curl and jq installed on your router… These are needed to be able to fetch the config of NordVPN Server. If not installed, go ahead and install
opkg install curl jq
After installation enter the command below to fetch the recommended server config:
curl -s "https://api.nordvpn.com/v1/servers/recommendations?&filters\[servers_technologies\]\[identifier\]=wireguard_udp&limit=1"|jq -r '.[]|.hostname, .station, (.locations|.[]|.country|.city.name), (.locations|.[]|.country|.name), (.technologies|.[].metadata|.[].value), .load'
Output:
uk1818.nordvpn.com #your endpoint host
178.239.166.185 #its ip address
London #city
United Kingdom #country
K53l2wOIHU3262sX5N/5kAvCvt4r55lNui30EbvaDlE= #Server public key
10 #Server load at the time.
Now you can use the data above to configure your OpenWRT WireGuard Interface.
