Hi folks,
For test purposes, I am trying to get RDP to work going through my PA-200 OS 6.1.4 to an internal PC.
I've been following several articles like this one, but not getting it to work.
I must be doing something wrong since my internet access rules are working fine.
Anyone see anything in my rules that look wrong?

I disagree.
Your Security Policy does NOT need to include internal IP.
As first is done NAT evaluation. This will tell firewall where packet needs to go to.
Then security policy is checked.
And last NAT is applied - just before packet is sent out to wire.
So security policy is checked when packet still has original IP but destination zone has already been changed in packet metadata.

Hey your second line shows your IP so no reason to hide it in first one.
NAT screenshot does not show right column that should include RDP server internal ip. So can't validate if this is there.
Other thing you can try is to enable bi-directional checkbox on second NAT rule. This will do the trick also create hidden NAT rule for incoming RDP traffic).
Hidden NAT policy is visible in CLI "show running nat-policy"

In my experience Raido is correct.

Thanks folks!
I will follow up and update this post later this evening.
This is my diagram trying to accomplish.

Ok, got it! Thank you for the feedback!
I forgot to adjust my gateway on internal server. Also do not need a bi-directional NAT rule. Just D-NAT and Internet S-NAT.
For the record, my correct rules below.
