Web Filtering rules dont work for a Network Group

Hello Guys,

I am back with another question. Here is the scenario. The Web Filtering rules work perfectly for an Individual Host(IP Address).

Now i have a bunch of IP address that i want to assign the Web Filtering. So what i have done is Under Network Definitions created a group with "Range" selected as Type and provided range of IP addresses that i want and provided Internal Interface to it. Then created another definition under type "Network Group" and added the above created entry in it. So basically i have network group entry that consist of range of Hosts.

Now i assigned the same Web Filtering profile to that Network group but the rules are not working. So please can anyone help me out here if i have done anything wrong, if so how can i correct it and if not then what can i do to make my web filtering rules to work.

Thanks,
Dhyanesh
