on New Rule
This will open the New Wizard for setting up the Rules,
You will find the four options there,
* Program /* for configuring the connection for specific
program */
-If you selected the Program, redirect the path of the
program and proceed,
* Port /* Specify the TCP/UDP port for configuring */
- In case you selected the Port, Enter the Port number.
Multiple port number can be entered by comma separated value or Range of the
ports first port-last port

Now you will get the option asking you to check the
checkbox having options when to apply the Rule you have created.
If you are in corporate domain and want to apply the rule
check the Domain
If the network domain is private, select the private.
Or select the public for public location
Click on Next
After this you will get the option to Name this new rule
and add the description for the other user (like if you are one of group of
administrator) and save the Rule. After this your rule will be applied to the
computer.
