Packet Filter
Packet filtering enables you to configure your router to block specified internal/external users (IP
address) from Internet access, or you can disable specific service requests (Port number) to
/from Internet. This configuration program allows you to set up to 6 different filter rules for different
users based on their IP addresses or their network Port number. The relationship among all filters
is “or” operation, which means that the router checks these different filter rules one by one,
starting from the first rule. As long as one of the rules is satisfied, the specified action will be taken.
Rule Name: Users-define description to identify this entry. The maximum name length is 32
characters, and then can choose application that they want from list box.
Internal IP Address / External IP Address: This is the Address-Filter used to allow or block traffic
to/from particular IP addresses. Input the range you want to filter out. If you leave empty or 0.0.0.0,
it means any IP address.
Protocol: Specify the packet type (TCP, UDP, ICMP, etc.) 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 filter rule, Forward (allows the packets to pass) or Drop
(disallow the packets to pass) this packet.
Internal Port: This Port or Port Range defines the ports allowed to be used by the Remote/WAN to
connect to the application. Default is set from range 0 ~ 65535. It is recommended that this option
be configured by an advanced user.
External Port: This is the Port or Port Range that defines the application.
Direction: Determine whether the rule is for outgoing packets or for incoming packets.
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
Log: Choose “log” if you wish to generate logs when the filer rule is applied to a packet.
Add: Click this button to add a new packet filter rule and the added rule will appear at the bottom
table.
Edit: Check the Rule No. you wish to edit, and then click “Edit”.
