Wired network through VPN and Wireless through ISP ip

Installing and Using OpenWrt
1

Hello,

Last Friday I received my new router (ZBT-WE1326 ) what I installed with the lastest Lede 18.06.1 snapshot.

I tried to configure my router that all the wired connections are going through openvpn (nordvpn) and the wireless connections 2.4 / 5 through the ip of the ISP.

I separate the zones but I don't get internet on my wireless unless I stop the VPN.

I would like to know how I can have an "active" wired VPN network connection and at the same time a wireless network active with a different (ISP ) ip address.

This thread uses Wireguard, but you setup policy-based routing in the same manner:
