Changing Port Numbers - Canon i-SENSYS LBP151dw User 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.
