Cerberus ADSL2 Wi-Fi Plus (P6331-6) Configuration / Virtual Server In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.
Cerberus ADSL2 Wi-Fi Plus (P6331-6) Item – Item number Type – Select TCP if you wish to search for connection-based application services on the remote server using the port number. Port Start & Port End – Enter the public port number & range you wish to configure.
