@alexandrud Another great option would be make a pre defined mode for rules like when you click on "Customize this rule before creating it" so all the rules are created in a customize way with one click. This mode will be less restrictive than "Customize this rule before creating it" (although you could manually delete the IP) so it won't save IP's in the rule, just ports, protocols and directions. With this we would avoid tons of duplicated rules/popups due to the IP's changing. This mode will provide better security or at lest better control for those who like to have a more granular control of the firewall. In order to avoid duplicates if the same program request to access to internet using a different port and we accept it, this rule will be merge with the existing one by adding the new port/s. If you add this feature and the 2 above I think will make WFC one of the best option out there.
