HP recommends adding a program instead of adding a port. Adding a 
program is easier and safer than adding a port because you do not 
have to know which port numbers to use, and the port is only open 
when the program is waiting to receive a connection. Only the 
specified application can use the port, whereas opening a port allows 
any application to use it.

The recommended configuration involves adding a program to the 
exception list. This solution provides the easiest configuration, as 
well as enables the firewall to open ranges of ports that can change 
each time the program runs.

To add a program exception:

1. Open Windows Firewall and click the Exceptions tab.

2. If the program is in the list, click to enable the setting. If the 

program is not in the list, click Add Program to display the Add 
a Program dialog box.

3. Click Browse to choose the program you wish to add as an 

exception, and then click OK.

4. Click Change Scope to view or set the scope for the program, 

and then click OK.

5. Click OK to close the Add a Program dialog box.

6. Click the check box to enable the program. By default, the 

program is not enabled in the list. 

If adding the program to the exception list does not resolve the 
application issue, you can add ports manually. You must first identify 
the ports used by the application. The most reliable method for 
determining port usage is consulting with the application vendor.

If the port number(s) for the process are less than 1024, it is likely that 
the port numbers will not change. If the port numbers used greater 
than 1024, the application may be using a range of ports, so opening 
individual ports may not resolve the issue reliably.

Once you have the port number and protocol, add an exception for 
that port.
