User's Manual

URL Filter: Blocks PCs on your local network from unwanted websites.

A detailed explanation of each of the following five items appears in the Firewall section below:

Packet Filter, MAC Address Filter, Intrusion detection, Block WAN PING and URL Filter.

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 address (es). 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.
