Openvpn GLInet Slate AR750S Client Routing

Hi

I have a GL AR 750 S router running the latest 3.105 Firmware. I have connected an Openvpn client from it to my QNAP Qhora SD Wan Router it works fins and clients on the Slate can browse the QHora Network.

How can i allow the QHOra Network clients to browse the slate network?
Slate is : 192.168.8.0/24
QHora is: 192.168.60.0/24

Please help.

Maybe you can just set up port forwards. It is easy.
