RV325 access rules not working

[Valadmin]

Hello All,

I am new here and far from top-level IT. If my question been answered, please point me. I could not find it.
I have RV325 and would like to open access to one machine from outside using RDP. For higher security, I would like to limit access from limited number of external IP. So,

If I am just forward port 3389 in the Setup-Forwarding- (3389 to 192.168.1.xxx) everything looks good, I can access from a remote computer.

If I disable port forwarding and add Access Rules 
Enable-yes, Action-Allow, Source interface-WAN1, Source - Any(for now any, later will limit to certain IP), Destination -192.168.1.xxx~192.168.1.xxx. I cannot access from a remote computer. 
Please help, I guess I am missing something. Spent a lot of time googling, no luck

If I would like to have access from more than single IP, should I create an identical rule(s) and specify each IP in each rule or there is a smarter way.

Thank you

Am I got so complicated question or it is a wrong place to ask?

Hi

If someone is interested, I figured it out

I had to enable forwarding in Setup-Forwarding

Next, in access rules, setup Deny rule from all IP

Next, Setup Allow rule with enabling specific WAN IP and give higher Priority than Deny rule

So, this way port 3389 is open for specific IP only
