1.4 Glossary

• LAN – Local Area Network

Local Area Networking (LAN) is the term used when connecting several computers together over a small area such as a building or group of buildings. LAN's can be connected over large areas. A collection of LAN's connected over a large area is called a Wide Area Network (WAN).

A LAN consists of multiple computers connected to each other. There are many types of media that can connect computers together. The most common media is CAT5 cable (UTP or STP twisted pair wire.) On the other hand, wireless networks do not use wires; instead they communicate over radio waves. Each computer must have a Network Interface Card (NIC), which communicates the data between computers. A NIC is usually a 10Mbps network card, or 10/100Mbps network card, or a wireless network card.

Most networks use hardware devices such as hubs or switches that each cable can be connected to in order to continue the connection between computers. A hub simply takes any data arriving through each port and forwards the data to all other ports. A switch is more sophisticated, in that a switch can determine the destination port for a specific piece of data. A switch minimizes network traffic overhead and speeds up the communication over a network.

• What is Router?

A router is a device that forwards data packets from a source to a destination. Routers forward data packets using IP addresses and not a MAC address. A router will forward data from the Internet to a particular computer on your LAN. A router also determines the best route that data packets should follow to ensure that the data packets are delivered properly.

• Firewall

A firewall is a device that sits between your computer and the Internet that prevents unauthorized access to or from your network. A firewall can be a computer using firewall software or a special piece of hardware built specifically to act as a firewall. In most circumstances, a firewall is used to prevent unauthorized Internet users from accessing private networks or corporate LAN's and

Internet.

A firewall watches all of the information moving to and from your network and analyzes each piece of data. Each piece of data is checked against a set of criteria that the administrator configures. If any data does not meet the criteria, that data is blocked and discarded. If the data meets the criteria, the data is passed through. This method is called packet filtering.

A firewall can also run specific security functions based on the type of application or type of port that is being used. For example, a firewall can be configured to work with an FTP or Telnet server. Or a firewall can be configured to work with specific UDP or TCP ports to allow certain

applications or games to work properly over the Internet.

• VPN – Virtual Private Network

Virtual Private Networking (VPN) uses a publicly wired network (the Internet) to securely

connect two different networks as if they were the same network. For example, an employee can access the corporate network from home using VPN, allowing the employee to access files and printers. Here are several different implementations of VPN that can be used.

• PPTP – Point-to-Point Tunneling Protocol

PPTP uses proprietary means of connecting two private networks over the Internet. PPTP is a way of securing the information that is communicated between networks. PPTP secures information by encrypting the data inside of a packet.

• IPSec – IP Security

IPSec provides a more secure network-to-network connection across the Internet or a Wide Area Network (WAN). IPSec encrypts all communication between the client and server whereas PPTP only encrypts the data packets. Both of these VPN implementations are used because there is not a standard for VPN server software. Because of this, each ISP or business can implement its own VPN network making interoperability a challenge.

• DHCP – Dynamic Host Configuration Protocol

DHCP is a protocol for dynamically assigning IP addresses to networked computers. With DHCP, a computer can automatically be given a unique IP address each time it connects to a network-

-making IP address management an easier task for network administrators. When a computer logs on to the network, the DHCP server selects an IP address from a master list and assigns it to the system.

• NAT – Network Address Translation200.

For a computer to communicate with other computers on the Internet, it must have an IP address. An IP (Internet Protocol) address is a unique 32-bit number that identifies the location of your computer on a network. However, with the explosion of the Internet, the number of available IP addresses are simply not enough.

This is where NAT comes to the rescue. Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers.

• Printer Server

Printer Server allow networked PC sharing the same printer on the network, only the networked PC has printer driver without physical connection directly with printer.

• DDNS – Dynamic Domain Name System Server

Domain Name System Server is a server that matches URLs (such as www.router-net.com) to numeric IP addresses. DDNS

• TCP/IP

Transmission Control Protocol (TCP) with Internet Protocol (IP). The main internetworking protocol used in the Internet.

• PPPoE – PPP (Point-to-Point Protocol) over Ethernet

PPP is the standard Internet protocol for dial-up connections. PPPoE is for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection.

• UDP – User Datagram Protocol

UDP provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection is not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the TCP.

• DMZ Host– De-Militarized Zone Host

DMZ is the portion of a private network that is visible through the network's firewalls. DMZ Host allows a local computer exposed to the Internet. Therefore, an incoming packet will be checked by Firewall and NAT algorithms in the router, then pass to the DMZ host when packet is not sent by hacker and is not limited by Virtual Server list. Besides, there are some IP protocols that does not have port number information. There is no way to use Virtual Server setting to forward incoming packet. Thus, DMZ host is the way to forward such kind of packets. If you try to enable DMZ host and setup Virtual Server, the precedence is Virtual Server and then DMZ.

For example, the incoming packet will be checked with Firewall rules, Virtual Server rules and then DMZ host.
