Trek N300 Travel Router and Range Extender PR2000 Port Filtering to Block Services Services are functions performed by server computers 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 players' moves. When a computer on the Internet sends a request for service to a server computer, the requested service gets identified by a service or port number. 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 service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF at www.ietf.org/) and published in RFC1700, "Assigned Numbers." The authors of other applications typically choose service numbers for those applications from the range 1024-65535. Although the Trek already holds a list of many service port numbers, you are not limited to these choices. You can often find port number information by contacting the publisher of the application, by asking user groups or newsgroups, or by searching. You can add and block specific Internet services by computers on your network. This process 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. Launch your browser from a computer or wireless device that is connected to the Trek. 2. Enter www.routerlogin.net or www.routerlogin.com in the web browser address bar. The login screen displays. 3. Enter the Trek user name and password. The user name is admin. The default password is password. The user name and password are case-sensitive. 4. Click the OK button. The BASIC Home screen displays.
