Services and Rules Regulate Inbound and Outbound Traffic The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P firewall lets you regulate what ports are available to the various TCP/IP protocols. Follow these two steps to configure inbound or outbound traffic: 1. Define a Service 2. Set up an Inbound or Outbound Rule that uses the Service These steps are discussed below. Defining a Service 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 other players' moves. When a computer on the Internet sends a request for service to a server computer, the requested service is 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 destination port number 80 is an HTTP (Web server) request.
