							ChangingPortNumbers
1469-07R
Ports serve as endpoints for communicating with other devices. Typically, conventional port numbers are used for major protocols, but devices that use these port numbers are vulnerable to attacks because these port numbers arewell-known. To enhance security, your Network Administrator may change the port numbers. When a port number has
been changed, the new number must be shared with the communicating devices, such as computers and servers. Specify the port number settings depending on the network environment.
To change the port number for proxy server, see SettingaProxy(P.411) .

							SettingaProxy
1469-07S
A proxy (or HTTP proxy server) refers to a computer or software that carries out HTTP communication for other
devices, especially when communicating with resources outside the network, such as when browsing Web sites. The client devices connect to the outside network through the proxy server, and do not communicate directly to theresources outside. Setting a proxy not only facilitates management of  trawc between in-house and outside networks
but also blocks unauthorized access and consolidates anti-virus protection for enhanced security. When you use
Google Cloud Print to print over the Internet, you can enhance security by setting a proxy. When setting a proxy, make sure that you have the necessary proxy information, including the IP address, port number, and a user name and
password for authentication.
