Please elaborate on which product you are using, what version, and which blades, and also explain the use case.

Is a Checkpoint 750 Appliance, version r77.20.40 and the blade im use is the firewall, to be honest its my first time with checkpoint. I have to open the ports of a server to use an aplication, even creating the rules does not allow me to access.

Your version of firmware is out of date.
The latest version for your hardware is: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk153433&partition=Basic&product=Quantum

When you say “doesn’t work” what is the precise behavior you see in the application?
What do you see in the logs when access is attempted?
Have you performed a tcpdump on the appliance to see if traffic is being sent to the target device?

Does your server actually listen on that port?
