to go to the right 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.
