Client Filtering
You can filter Internet access for local clients based on IP address, application type
(i.e., HTTP port), and time of day.
For example, this screen shows that clients in the address range 192.168.2.50-99
are permanently restricted from using FTP (Port 21), while clients in the address
range 192.168.2.110-119 are blocked from browsing the Internet from Monday
through Friday.
