  1. Obtain NordVPN API access token from https://my.nordaccount.com/dashboard/nordvpn/access-tokens/
  2. Fetch NordVPN NordLynx (WG) private key from API https://api.nordvpn.com/v1/users/services/credentials - private key is in value of nordlynx_private_key JSON [1]
  3. Fetch NordVPN server configurations from API https://api.nordvpn.com/v1/servers/recommendations?filters[country_id]=<COUNTRY_ID>&filters[servers_technologies][identifier]=wireguard_udp [2] - find desired server where per server JSON keys are:
    3.1. station - WG peer endpoint IP address
    3.2. technologies[].identifier["wireguard_udp"].metadata[].name["public_key"].value - WG peer public key
  4. on ROS:
    4.1. add Wireguard interface with private key from 2nd step
    4.2. add Wireguard peer for NordVPN server with public key and endpoint IP from 3rd step, also set there port to 51820 and Allowed Address to 0.0.0.0/0
    4.3. add IP address for created Wireguard interface with address value 10.5.0.2/24 and network 10.5.0.0
    4.4. add firewall NAT rule in srcnat chain and created Wireguard interface as out interface for masquerade action
    4.5. setup routing and firewall rules according to your current configuration - see here for some example

  1. NordVPN API endpoints are protected with basic auth where token is username and API access token is password from previous step ( Authorization header with value: Basic base64(username:password)) ↩︎

  2. value for <COUNTRY_ID> with desired country ID can be fetched from API https://my.nordaccount.com/api/v1/servers/countries (eg. for Spain is 202) ↩︎
