    TW-EA510 version 4 ADSL2+, WLAN 802.11g, VPN, Firewall Router Virtual Server (“Port Forwarding”) 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”.
