Filtering Options

IP/Port Filter
Choose ADVANCED > Filter Options > IP/Port Filter to go to the following page.
The page shown as the figure appears on the right. The IP/Port Filter in this page
is based on IPv4 protocol.
Entries in the table are used to restrict certain types of data packets through the
gateway. These filters are helpful in securing or restricting your local network.
For example, select protocol as IP, rule action as Deny, direction as Downstream
and fill the Source IP/Dest IP, which means downstream IP packets matching the
source IP address and the destination IP address cannot enter the internal
network.
