Common Port Numbers for Internet Applications
Typically you will not need to know which TCP/UDP port number an Internet application uses to transfer date. However, if you need to configure a particular application or protocol to use "terrestrial mode" (See Turbo Internet - Terrestrial Properties for more information) you will need to know the port number of the protocol. The table below list TCP/UDP port numbers for common Internet applications and protocols.
