Hello seth@d2ms.com,
In order to isolate the issue let me ask you, Is the RV320 behind another device? do you have that public IP address configured on the RV320's WAN?
In any case, please go to Setup--->Forwarding and verify if there is any forwarding rule configured in the Port Range Forwarding Table, if there is you can delete it, after that those ports should not be open.
Have a great day!
