Guidelines To help you connect More Than One computer To Your Broadband Connection

Ever since the advent of the Internet everyone has been accessing it either utilizing broadband or high-speed connectivity even at home. In fact today many people have more than one device that needs to be connected to the Internet; it could be one or more computers or it could be other mobile devices like a smartphone etc. which implies that the need for a router cannot be ruled out. Given below are the tips of how you can utilize a router to connect more than one device to the Internet.

Get to know what an IP address is
Typically this is a set of numbers that come in the nnn. nnn. nnn.nnn form and the nnn stand for any set of one to three digit numbers. Every computer that is a part of a group of computers that are connected to the Internet will have a unique IP address, just like how a house has a special number that is all its own. When you subscribe for Internet connectivity, the provider from whom you are taking the connection will provide you with the IP address. If you have more than one computer or other device that requires to be connected to the Internet simultaneously you will be provided more than one IP address, but you will also be able to connect to the Internet using a single IP address.

How to connect a single computer to the Internet
It is really very easy to get your computer connected to the broadband Internet. All you have to do is to connect one end of a network cable on to the modem and the other end into the computer network card port. You will be provided with an IP address from your provider. An IP address can look like this 24.24.50.17 and once you have been allotted an IP address that will always be the IP address fro your computer.

If you happen to try to create a website or page and send a request to the server, it can immediately identify the IP address from which the request came and it will send requisite details through the Internet to your computer’s IP address, which you will naturally receive. This could be compared to a postal mail that is sent to your home address. The address on envelop, tells the postman where exactly to deliver it.

How you can connect more than one computer to high speed broadband Internet
You must be wondering how with a single IP address you can connect more than one computer to the Internet. You must also be wondering how the server will know which computer sent a request for a web page if you are allotted only a single IP address and there are multiple computers connected through the same IP address to the Internet. Now this can be explained by taking the example of your living in an apartment rather than a single house. Your apartment has a specific number, and when someone sends you mail other than the address of the apartment building they will also include the number of your apartment so that the mail is delivered at your door. This only shows that the apartment number is one of the internal parts of your apartment building with different apartments having different and unique numbers. In the same way when you connect more than one computer to a single IP address, each computer that is connected through one single IP address will be assigned specific IP addresses and this is done using a router.

A router is a piece of equipment that is linked straight to your modem and every computer or other device is linked to the router and not the modem. This implies that every device connected through the router will be allotted unique IP addresses by the router instead of it being provided by your ISP. When the request for a web page is made though it is sent through your ISP’s address, but it will be allotted through your router, which means when there is a reply it will be the router that gets it and it is the router that will pass this reply to the requisite computer.

What you have to understand is the router too will have an address in that locality and this address will be akin to the local IP addresses of your computers. This implies that the router will have two IP addresses; the external IP address given by the ISP and a local address also allotted by it. This is how the router is able to connect to the Internet as well as the network in your locality. Please note that the 192.168.xxx.xxx addresses are unique IP addresses that are specially kept aside for Local Area Networks.

How to manage an FTP or Web server on your particular network system
Now suppose you would like to create an FTP or Web server when you have more than one computer connected to the Internet. This is no trouble either. You will have to install the requisite application on which ever computer you want and you ask somebody to connect it by giving the local IP address of your FTP server. However they are unable to connect up. What you have to realize is that you have only given them your local IP address and not the IP address that you have been allotted by your ISP. The point is that your computer can be connected to other local computers in that address, but it cannot connect to the Internet without the IP address given to you by your broadband provider. Only then can someone connect to your FTP server through the Internet. It is your router and not your computer that is allotted the IP address by the provider and since that IP address is unique, is it any wonder that they have not been able to connect to your FTP server?

Now you also have to understand that a port is a channel that is numbered to transmit information via a network system, and routers have the capacity to pass on data on a port to a certain computer. Of course the fact remain that you cannot actually see the data being transmitted as it is a virtual channel that is utilized to send and receive data. In the case of FTP servers the port number is 21 by default, but another port can also be utilized.

To do this, open the setup in your router and search for the option “port forwarding” that is being sent through port 21 and forward it automatically to the FTP server by ascertaining that you give the internal IP address of your FTP server and the port number. Remember to save these details. When someone wants to get to your FTP website, they will have to utilize the IP address that is assigned to the router by your broadband provider and the router in turn will notify the server. The same thing can be done to set up your web server, but here the port number will by default be 80.

Just for your information, the router will assign IP addresses to all the computers that are linked to it one after the other in the same order. This implies that the first computer that is connected to the router will get the first IP address that can be availed of , the second computer that gets linked to the router will get the next IP address and so forth for as many computers that are connected to it. By chance you have an FTP server it could be simpler to allot static addresses to the different computers connected to the router such that the FTO server will constantly have the same IP address. Remember than when you are setting up a web, an FTP or any other server, it is imperative that you utilize the router’s IP address provided by the ISP so as to get access to the server. Once you do then you will be required to pass on the required port to the server.
