Packet Filter

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.

Rule Name: User dened description for entry identication. The maximum name length is 32

characters, and then can choose an application that they want from the listbox.

Internal IP Address / External IP Address: This is the Address-Filter used to allow or block trafc

to/rom particular IP address(es). Input the range you want to lter out. If you leave these four elds

empty or enter 0.0.0.0, it means any IP address.

Protocol: Specify the packet type (TCP, UDP, TCP/UDP) that the rule applies to. Select TCP if

you wish to search for the connection-based application service on the remote server using the

port number. Or select UDP if you want to search for the connectionless application service on the

remote server using the port number.

Action: If a packet matches this lter rule, forward (allows the packets to pass) or drop (disallow

the packets to pass) this packet.

Internal Port: This Port or Port Range denes the ports allowed to be used by the Remote/WAN

to connect to the application. Default is set the range from 1 to 65535. It is recommended that this

option be congured by an advanced user.

External Port: This is the Port or Port Range that denes the application.

Direction: Determine whether the rule is for outgoing packets or for incoming packets.

Time Schedule: It is self-dened time period. You may specify a time schedule for your

prioritization policy. For setup and detail, refer to Time Schedule section.

Log: Check the checking box if you wish to generate logs when the ler rule is applied to a packet.
