Packet Filter
Packet filtering enables you to configure your router to block specific internal / external users (IP
address) from Internet access, or disable specific service requests (Port number) to / from the
Internet. This configuration program allows you to set up 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:
User defined description for entry identification. The maximum name length is 32
characters, and then can choose an application that they want from the listbox.
IP Version:
select either IPv4 or IPv6 base on need.
Internal IP Address / External IP Address:
This is the Address-Filter used to allow or block traffic
to/rom particular IP address(es). Input the range you want to filter out. If you leave these four fields
empty or enter 0.0.0.0, it means any IP address.
Protocol:
Specify the packet type (TCP, UDP, TCP/UDP, RAW, Any) 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. Only when
RAW
is selected, then you can type the protocol
number (0-254) to identify the protocol that you want the filter applies to. When
Any
is selected, it
means the filter will applies to any protocol.
Protocol Number:
type the specific protocol number when
RAW
is selected in the above field.
Action:
If a packet matches this filter rule, forward (allows the packets to pass) or drop (disallow the
