How to connect multiple computers to a broadband Internet connection
Broadband or high-speed Internet connection is what many users are currently in use in their home. Along with high-speed Internet, many users can also use a router to connect multiple computers to the Internet. This document describes how to use a router to connect multiple computers. Easier to understand, I will use when you live as a comparison to how the computer is connected to the Internet.
What is an IP address?
IP addresses consist of a seriesnnn.nnn.nnn.nnn numbers in the form: nnn is the start of a three-digit number. An IP address is unique for a single computer in a network, just like at home, has a unique address. Provided a connection to the Internet, an IP address from your Internet service provider (ISP). In some cases, the ISP can have more than one IP address, which you can connect to multiple computers. As we shall see later, but it is still more computerswith a single IP address.
Connecting a single computer
Connecting a single computer to your high-speed Internet is very easy to do. Simply connect a network cable to the modem and then into the network card in your computer. Your computer will be assigned an IP address from your ISP. For example, if your ISP assigns you the IP address 24.24.50.17, then the IP address of the computer.
WhenSend a request to a server, such as a Web page, the web server knows what IP address that made the request. The information is then sent via the Internet and back to your computer. This is like when someone sends mail to your home. The address on the e-mail can be delivered at home and not elsewhere.
Multiple computers
How can connect multiple computers, if only one address is assigned? If you have a network request –First, as you know which computer on which the requested page? Let our home analogy a step further. Suppose, instead of living in a house that you live in an apartment. If someone sends you e-mail, not only address but also an apartment. This figure is inside your house apartment and each apartment has its own number. Similarly, multiple computers can connect to the Internet when they are there own local IP address. This canprocessed by a router.
A router is a piece of hardware that connects directly to the modem. Each computer is then connected to the router instead of the modem. Now, instead of the computer with the IP address from the provider, the router is now assigned the IP address provided. This is comparable to the router via the apartment.
The beauty of a router is that you can assign your own local IP addresses. If you use a computer to the router hoursreceives the IP address of the router, as each house has its own assigned number. If we now make a request to a Web page, the request is sent to the provider the same address, but this time is to assign to the router. If the Web page is returned, the router receives the request and sends it locally on your computer, the requested page.
The router also has its own local address, which is the local IP addresses of computers alone. Then there is theRouter has assigned two addresses: one provided by the external provider and one local, who has made available. This allows the router to connect to the Internet and local network.
Note: The address 192.168.xxx.xxx are special IP addresses for local area networks (LANs) are reserved.
Managing a Web or FTP server on the network
Let's take a look at this scenario. You have a router that connects multiple computers to the Internet. But now I want To create an FTP or Web server. No problem. The installer software is required on a computer network, "said someone outside the network, the local IP address of the FTP server and try to get in touch. Then he discovered that he can not connect. Why? Like something to someone list by simply pointing your home number and no address.
The IP address assigned to your computer on the network. You can connect to this> Computer networking, but not from the Internet. You need your ISP assigned IP address (assigned to the router) to have someone from the Internet to connect to FTP server. The problem is that the router assigns the IP address and the computer, and as an IP address must be unique, as two computers can share the same IP? The answer: you can not, but it is not.
Routers are able to provide information on a door to the fronta particular computer. A port is a channel numbered according to which data can be sent to a network. You can not physically see, as it is a channel length of the virtual network used for sending / receiving data . For FTP servers the default port is 21, but another port can be used.
Open the router configuration and look for the option of port forwarding. Enter the internal IP address of the FTP server and the port number and then save the information. When a user tries toAccess to the FTP site must be assigned to the ISP's IP address for the router. The router will then establish that the data is sent on port 21 and then forward it automatically to the FTP server. A web server is setup the same way, but the default port is in Rule 80;
Note: By default, a router dynamically assign IP addresses to computers connected to it. This means that the first computer is connected to the router to get the first available IPThe address and the next to get the second, and so on. If you assign an FTP server for management, may be easier to have a static IP address on your computer in order to ensure that the FTP server is always the same IP address.
This article describes how to connect one or more computers to an Internet connection. It 'important to remember the following:
If you have a computer connected directly to the modem, so that the computers are assigned the IP address from your ISP.
WhenUsing a router that the router's IP address assigned by your ISP. Every computer connected to the router receives a local address of the router.
Router, the IP address of the provider and a local IP address. This allows you to connect to the Internet and network connections.
When you set up a computer as FTP, Web or communicate with other servers on the Internet, it is important to use the IP address of the router to access the server. Is therefore necessarySubmit application port on your server.
