Instead of making numbered rules, you can make rules that lets the application use any range of ports. They are called application rules. To make them, run the procedure below:
Temporarily switch Kerio to advanced mode so it can create a rule foryour new application. Please open Kerio. Then, click the Network Security tab, found on the left. Now on the right you'll see a list of applications. Find the one called "Any other application." Click each of the 4 columns until the columns read ASK ASK ASK ASK. Then click the Apply Button.
Now, try running that application. Kerio will pop up a dialog box that asks you to click "PERMIT" or "DENY" to an application.
Be sure to CHECK the checkbox above these choices to create a rule for this application, and then click the "PERMIT" button. Do this for each time you receive the message. Use the application as normal, and then exit the application. Kerio has now made a rule for this program. Go back to Kerio and change "Any Other Application" back so they read in this order:
DENY PERMIT DENY PERMIT by clicking each of the 4 columns until they are changed to those values, then click Apply. Kerio is now back in Simple mode, and you have successfully permittedthis application on to the Internet.
