How to Configure NordVPN and VietPN on Padavan Firmware

PADAVAN is well known for its stability and relatively simple interface. Routers such as the Newifi 3D2 can run it well. See the Newifi 3D2 firmware collection for related information.

This guide shows how to integrate NordVPN or VietPN into the router. Once connected to Wi-Fi, clients can use the VPN connection without installing a separate application on each device.

1. Configure the VPN Client → Settings menu

Enable VPN and enter the following values:

• Remote VPN Server (IP or DNS host): enter a NordVPN hostname. Use the NordVPN server tool to obtain one. For example, a Vietnam server may look like vn20.nordvpn.com, while a US server may look like us8923.nordvpn.com.

  

• Login: your NordVPN or VietPN account username.
• Password: your NordVPN or VietPN account password.
• Authentication Algorithm: SHA-512.
• Encryption Cipher Algorithm: AES-256-CBC.
• Enable LZO for Data Compression: Disable.

Open OpenVPN Extended Configuration and paste:

2. Click Apply, then open OpenVPN Certificates & Keys

• Download the NordVPN server certificates from the official archive .
• The ZIP contains two certificate files for each server.
  • For example: vn20_nordvpn_com_ca.crt and vn20_nordvpn_com_tls.key.
  • Copy the contents of xxxx_nordvpn_com_ca.crt into the ca.crt field.
  • Copy the contents of xxxx_nordvpn_com_tls.key into the ta.key field.
    • xxxx is the server name. If the remote server is vn20.nordvpn.com, use vn20_nordvpn_com_ca.crt and vn20_nordvpn_com_tls.key.

• Click Apply.

Turn off Wi-Fi on the phone, reconnect to the router, and check whether the public IP has changed. If it has not, review the server, credentials, certificates, and transport settings.
