I've got a port exception that I've added to Windows Firewall. And under Scope, I'm able to add specific IP addresses allowed, each separated by a comma. The problem is, how can I enter a range of IPs?
I don't mean 192.168.1.0/24 kind of thing. I have a user who's IP keeps changing, and they're located in Austria. Their IP is always 91.113... I'd basically like to allow that.
Or, is there a better solution? I'm not keen about opening up such a wide range of IPs but his IP is changing daily and is really frusterating for everyone. Our dynamic IP here at the office in Canada only changes every 4 months, so I was hoping that it wouldn't be a big deal to restrict.
Thanks for the insights.
