Firewall predefined rule property cannot be modified

Using a stand alone Windows Server 2012 Standard edition (no Active Directory),

I Tried to establish a simple remote desktop with a custom port number, but could not modify the port number in the Firewall inbound rule,

when I open the inbound property I get the next message: "This is a predefined rule and some of its properties cannot be modified"

I have tried to set it up like this: New rule -> predifined drop down list -> Remote Desktop -> check mark rules -> Allow the connection.

but still get "This is a predefined rule and some of its properties cannot be modified"

Thank you in advance.

Solution 1:

It looks like you're trying to "redefine" a rule for a predefined service when I think you need to make a custom rule for the port you want RDP to listen on. Then you'll need to change thr port that RDP is listening on. Here's an article that explains how to do it in Windows Server 2008 R2. I imagine it's going to be the same in Windows Server 2012.
