LSWN Individual Assignment Necessary Equipment and Software The equipment needed for the internet connection implementation is a modem, router, fiber optic cable, CAT 5 UTP cable and a network card.

Figure 1 Overview of the internet flow

Figure 2 Modem (Huawei Echolife HG850a GPON Terminal)

A modem is equipment that is used to transmit and receive the data between your computer and your internet service provider. All the binary code data from the computer is converted into analogue signal and is travels over the destination via telephone or cable line. When the data reach the destination, the modem will convert the analogue signal back to binary coded data, and

Leim Jing Jie TP025470

Page 5

LSWN Individual Assignment the data is now readable by the computer. In a simpler definition, a modem is a device that converts the analog signal into data or vice versa.

Figure 3 Dlink Router (TM, 2013) The router is a device that forwards the packet data in the computer networks. This device normally is connected to at least 2 networks. It is located at the gateways, the place where 2 or more networks are connected. (Elizabeth, 2010) By using the modem and router, the user will able to supplies internet and transmit the internet signal connection to different users in the home. The user can use their wireless devices like laptops, tablet or PC to use the signal and get the ability to access to internet. This device can be used as hardware firewall and provide better protection to the user against the hacking than the software firewall. Moreover, it unlike software firewall, will consume computer resources. (Christina, 2010) A wireless adapter is needed to get the internet connection. It adds the wireless connectivity to a laptop or desktop. It can be in the form of USB or card formats. (Ben, 2010)

Figure 4 Cat 5 UTP cable (Alan, 2010) Cat 5 UTP cable is used to allow the transmission of internet connection between routers to the end user devices or modem to router. This kind of cable can support 10/100 Mbps Ethernet network.

Figure 5 Fiber Optic (James, 2010) Fiber optic cable is containing bundle of glass threads, which capable to transmit the message modulated onto light wave. It carries more data and can have a greater bandwidth. It is used as the data transfer medium from the internet service provider to the internet subscriber home. (Cecilia, 2009)

There are some software needed to implement the internet connection for the home, which are firmware, web browser and Ubuntu operating system. Every routers is containing a built-in programmable logic called firmware. It is used to implement the networks and security for the router. Every brand firmware come with different graphical user interface, and user can use the features of the routers once they enter the login information of the router. (John, 2010)

LSWN Individual Assignment Before started to set up the internet connection, the user should have a web browser in the computer, else they will unable to surf the internet. The Ubuntu Operating system has a default web browser, which is Mozilla Fire Fox and it can be used for configuration. The users also can install or have others updated Java-enabled web browser in the market to do the configuration of the router. The table below shows the recommendation of web browser that can be used: Without an updated Java-enabled web browser, the user might cant access to the web-based configuration utility. Internet Explorer 6.0 or higher

Camino 0.8.4 or higher

Netscape 8 or higher

Firefox 1.5 or higher

Mozilla 1.7.12 (5.0) or higher Opera 8.5 or higher Safari 1.2 or higher (with Java 1.3.1 or higher) The computers that are used must come with an operating system, Windows, Macintosh or Ubuntu. In this project, all the users’ devices must come with Ubuntu operating system. Without the operating system, web browser and the modem router stated above, configurations of network will not success.

By default, all SSID name is end with @Unifi. When your neighbor saw that name, they will know this is the default setting of the internet connection. They might play around with it or might find ways to crack or try to access to the network using the default username and password mention above. If the user does not want others to know the SSID name of this device, he or she can enable the hidden wireless in wireless setup page. The users are required to know the SSID name of the devices in order to join the network. Change Wi-Fi Security Key By default, if the internet connection is not configured, password is not required to use the internet, or if configured, it usually used password that can easily cracked by others. The user should enable the WEP and WPA/WPA2 function in the router and enter your preferable alphanumeric password in the space given. The WEP and WPA/WPA2 security protocol can ensure that your wireless LAN is secured and it would be hard for the unauthorized user to hack or sniff the wireless LAN.

LSWN Individual Assignment Limit the router IP address Pool The devices that join the network can be identified using IP address. This router comes with a built-in DHCP server. The DHCP server will assign 1 IP address to the device when it joins the network. By limiting the IP addresses of your router, the lesser the chance for the unauthorized user from accessing the network. If the user for the wireless LAN is less, you can set a range of DHCP IP address from 192.168.0.1 to 192.168.0.10. It only allows 10 devices on using the network. The photo below shows the steps of limiting the router IP address Pool.

Figure 53Limit router IP address pool

The user can choose to disable or enable the server. The user can set the IP address range for the router. They can also add the clients of DHCP by entering the computer name, IP address, and Mac address of the devices.

LSWN Individual Assignment Port forwarding Concept and Application Port forwarding also called as port mapping. It is a useful method to preserve public IP addresses, protect the servers and clients from unwanted access. The services and servers of the network can be hided using port forwarding. Port number is used to identified the services. For example web traffic uses port number 80. If you host a Web server in your home that is accessible on the public internet, the port forwarding panel in the router will configured to direct Web packet of port 80 to IP address of the Web server in your home. Moreover, port forwarding can limit the access to and from a network. Port forwarding is important. It can be used to keep unwanted traffic off the networks.Invalid source specified. Internet

Open Incoming Port 80

Direct Port 80 traffic to IP address of Web Server

Web Server

The diagram above shows the process of port forwarding, which allows the users from accessing the web server from anywhere using internet. Port forwarding allow the users to open and choose the range of port number that they would like for the user of certain IP address for some application incoming and outgoing traffic activity.

Leim Jing Jie TP025470

Page 38

LSWN Individual Assignment Implementation of port forwarding Firstly, the router’s IP address is entered into the address bar of the web browser of the users. Secondly, the users are required to enter their username and password for the router. If you have forgotten your username and password for the router, you can click the reset button to reset it back to factory defaults. After that, you can search for the factory default setting login information online.
