RV042G - How to permit only two internet IPs to port forward?

Hi, first time using these forums. We have a RV042G. We need to permit a company we do business with to port forward a port (5900) to one of our internal machines (192.168.1.122, for example), but we only want to permit the forwarding if the request comes from one of two internet IPv4 numbers used by that company. If any other IPs come knocking on port 5900, we want that traffic denied.

How do we set that up under this router? I tried to add it to the Firewall Access Rules but it doesn't seem to be working as it seems to be letting ALL internet traffic in (when I run an external port scan).

Thanks

Good Afternoon,

Did you set the ACL as the screenshots that I attach?

Regards.
