Inbound to Peplink Network from OpenVPNWan Connection

I am trying to get to the inside network (192.168.50.x) from the OpenVPNWan connection. The connection to the VPN network works correctly but I am unable to reverse nat through the OpenVPNWan connection.

I am able to ping the IP of the Peplink from inside the VPN network.

I am able to contact the internal network with port forwarding but I would like to contact the entire internal network.

If I turn on IP Forwarding I loose all connection to the vpn network even with outbound policy.

Thanks
