So some exe application trying to get to internet, firewall alert is shown, and
you would like a specific rule to be one-click created:
Allow for that specific IP, for any port,
(but ask again if any other IP will be requested).
Seems alert frequency setting is exactly supposed way to control these rules, but for me either alert is shown again for each new port (“Very High” or “High”), either it allows any IP at once (“Medium”) =(instant full trust).
May be there is some other setting to allow any port by default?
