I'm not sure if this is already available, but I am having to block numerous attempts to attack my systems from the same group of IP addresses; octet 0 is ****** (******.b.c.d) and octet 1 is YYY (a.YYY.c.d) so it would be ******.YYY.c.d.
Is it possible to implement a global rule for the firewall such that it covers everything under ******.YYY so I don't have to keep adding them in one by one.
In addition, would it be possible to implement sorting by IP address in the rules list, particularly when you are performing an absolute block (all apps, all ports) by means of a simple click on the column header, similar to how most column sorting takes place?
