There is no option to block an IP Range. Nor ability to block ports.
Since glasswire is replacing other firewall apps. This option needs to be in there because it’s not a good idea to stack firewall apps on top of each other.
It’s a hassle to do this directly within windows firewall control panel. And you could put convenient enable/disable toggles on these rules.
I cannot stress how important this is. because first thing a user does is “ALLOW” their browser full access. Yet there many bad actor scripts that spread out their spyware though multiple dns subdomains. But you can easily stop them totally dead because at the end of the day they route themselves to just a couple of central servers within a IP Range. It is NOT enough to just block a single IP address. or attempt to block a single dns address.
Windows has full CIDR/IP blocking ability. This is the equivalent of a Wildcard block.
There are also many dangerous ports left open by windows. Which need to be blocked. Glasswire has no facility to enter port blocks.
Both of these are built into windows native firewall. But you could provide to option to control these
I have found GlassWire to be more convenient to use than all the other firewalls. It also implements an extremely important feature of keeping a timeline of past activity. Windows has a habit of only running traffic through apps and services when the computer is idle and the screen has been off. As SOON as you wake it up. These apps stop running traffic. Glasswire remembers them and even tells you. This feature alone makes me want to keep glasswire.
