First, please check whether your router supports secure VPN connections. Many times, VPN configurations are not supported by most ISP-issued routers. Also, note that NordVPN’s servers have stopped supporting PPTP and L2TP/IPsec connections since December 2018. To find out if your router can be used for a VPN connection, you need to read the user manual, contact your retailer or check the settings of your router. Your router also has to support OpenVPN as a “Client” and not a “Server.” This will allow it to make connections with NordVPN servers.
