Port forwarding from RED to OpenVPN Client

[Guest]

Hello guys,
I'm trying to set up a port forwarding in order to NAT all the traffic directed to one of my public IP addresses on RED to one of the OpenVPN clients with static IP address.

As of now, I added a simple rule (on NAT/PORT FORWARDING page) like this:

Is it right? What else should I check/set to make it work?

Thank you very much,
