Add IP Range as Exception
Currently I'm having to add a network exception for each IP address I want to communicate with across my network. With IP's being leased out via DHCP, this can sometimes be frustrating and annoying if an IP address changes. Is it possible to add an IP range to network exception [e.g. 192.168.0.???]?
Thanks in advance

Both IP ranges and Port ranges are supported and work in the following format examples:
IP: 192.168.0.1/24
Port: 1000-1005
Let me know if you need further assistance.0 -

Thanks for your response.
Shall "192.168.0.1/24" be interpreted as IP range 192.168.0.1 - 192.168.0.24 inclusive, on any port from 1000-1005?
If so, I tried entering 192.168.0.1/255 into Custom Remote Address, to allow any computer from my network, for a new rule and I was returned with a Firewall Error : Invalid remote addresses. Please input upto 4IPs or networks.
I've also tried 192.168.0.1-255 and 192.168.0.1-192.168.0.255. All that happens is that everything after ".1" is removed from the IP entry.
Would appreciate your guidance.

192.168.0.1/24 is the CIDR notation for IP 192.168.0.1 and a netmask of 24 bits set to 1(i.e. 255.255.255.0). That means all IPs in 192.168.0.0-192.168.0.255.
Should you want to add a specific IP to the list, you would use 192.168.0.1/32, meaning all 32 bits-all of them- of this IPv4 are significant, so only that one IP.
Please see the wikipedia article for more details or search for CIDR calculator in your favourite search engine for a hand.0
