Add Keyword

button and click

the

Apply

button.

The Keyword list supports up to 32 entries. Here are some sample entries:

Block Services (Port Filtering)

Services are functions that server computers perform at the request of client computers. For

example, web servers serve web pages, time servers serve time and date information, and

game hosts serve data about other players’ moves. When a computer on the Internet sends a

request for service to a server, a service or port number identifies the requested service. This

number appears as the destination port number in the transmitted IP packets. For example, a

packet that is sent with the destination port number 80 is an HTTP (web server) request.

The Internet Engineering Task Force (IETF at

) has defined the service

number for many common protocols, which are published in

RFC1700, Assigned Numbers

.

Application developers typically choose service numbers for other applications in the range

1024 – 65535. Although the router already holds a list of many service port numbers, you are

not limited to these choices. You can often determine port number information by contacting

the publisher of the application, by asking user groups or newsgroups, or by searching.

The Block Services screen lets you add and block specific Internet services by computers on

your network. This is called service blocking or port filtering. To add a service for blocking,

first determine which port number or range of numbers the application uses.



To block services:

1.

Select

ADVANCED > Security > Block Services

.

2.

Select either the

Per Schedule

button or the

Always

button.

3.

If you selected Per Schedule, specify a time period in the Schedule screen.

4.

Click the

Add

button to add a service.
