Changing Port Numbers - Canon LBP6230dw Manual

Changing Port Numbers

Ports serve as endpoints for communicating with other devices. Typically, standard port numbers are used for major protocols, but
devices that use these port numbers are vulnerable to attacks because these port numbers are well-known. To enhance security, some
network administrators prefer to change the port numbers. When a port number has been changed, the new number must be shared
between communicating devices, such as computers and servers. If a port number changes, set it on this machine as well.
