Note: the filtering settings should be divided into two parts. Part 1 is the Exact Filter List and Part 2 is the Default
Filter Policy. The priority of Exact Filter List is higher than Default Filter Policy. It means that while Router receive IP
packets from WAN side, it will check the Exact Filter List first, if the IP packets mismatch the Exact Filter List, then
Router will execute the Default Filter Policy.
