IP Filtering
Packet ltering enables you to congure your router to block specic internal / external users (IP
address) from Internet access, or disable specic service requests (Port number) to / from the
Internet. This conguration program allows you to set up different lter rules for different users
based on their IP addresses or their network port number. The relationship among all lters is “or”
operation, which means that the router checks these different lter rules one by one, starting from
the rst rule. As long as one of the rules is satised, the specied action will be taken.
Outgoing
All outgoing IP trafc from LAN is allowed by default, but some IP trafc could be blocked by
setting up lters.
Click Add to enter Add IP Filter -- Outing screen to create a lter to identify the outgoing IP trafc.
Filter Name: User dened description for entry identication. The maximum name length is 32
