User Guide
TCP/IP
A suite of communications protocols used to connect hosts on the Internet. TCP/IP uses
several protocols, the two main ones being TCP and IP.
UDP
User Datagram Protocol
One of the TCP/IP suites of protocols for data transfer, which allows an application
program on one machine to send a datagram to an application program on another
machine.
Virtual server
A virtual server allows you to direct incoming traffic from the Internet (identified by
protocol and external port) to an internal server with a private IP address on the LAN.
WAN
Wide Area Network
WAN usually refers to a network which covers a large geographical area, and uses
communications circuits to connect the intermediate nodes. A major factor impacting
WAN design and performance is a requirement that allows communications circuits to be
leased from telephone companies or other communications carriers.
WPA-PSK
Wi-Fi Protected Access-Pre Shared Key
WPA is an industry standard based on a subset of an early draft of 802.11i. WPA replaces
WEP's keying mechanism with a more robust system, called Temporal Key Integrity
Protocol (although TKIP is still based on RC4 encryption). WPA adds a strong message
integrity check and allows for authentication using 802.1X.
