This article shows you how to access a blocked site or web content using a computer or mobile device connected to a restricted LAN. You can do this using a proxy server or a VPN connection (from English "Virtual Private Network") or using your smartphone as a HotSpot.

Steps

Method 1 of 4: Use a Web Proxy

Step 2. Log in to the website of the proxy server you want to use

There are countless websites that offer this type of functionality, but the most used and known are the following:

  • ProxFree -
  • HideMe -
  • CroxyProxy -
  • In case the proxy servers indicated by the LAN you are connected to cannot be accessed, search online using the online proxy free keywords, then consult the list of results until you find a proxy server that you can access.

Step 3. Locate the address bar and select it with the mouse

The structure of the Web Proxy interface is very simple and in most cases consists only of a text field called "URL" or "Website" placed in the center of the page.

Step 4. Enter the URL of the website you wish to access

Type the address of the requested page into the text field indicated (for example "www.facebook.com").

Most Web Proxies do not allow you to perform an online search directly from your site, so in this case you will first have to access a normal search engine (for example Google) using the web interface of the proxy server and only at this point enter the keywords you want to search for

Step 5. Press the Enter button

At this point you will instruct the proxy server to load the content published by the requested website.

Since the proxy server will have to log in to the requested web page and then reroute its contents to your computer, the page loading process may take a few seconds slower than normal

Using the browser tab relating to the Web Proxy you have selected you will be able to access all the web pages that were previously blocked. However, remember to always and only use this browser tab if for any reason you open a new window or a new tab you will no longer be able to access blocked content.

Step 1. Choose a VPN service

As in the case of proxy servers, there are countless VPN services available and usable. Some of the more well-known and used ones include NordVPN and ExpressVPN, but feel free to use the one that best suits your needs (or your budget if you've chosen to use a paid VPN service).

  • If the firewall or access control software you are trying to bypass is installed on a public network (such as a library) or on a work or school computer infrastructure, it is very likely that you will not be able to use. the chosen VPN service, unless you can change some configuration settings of the computer you are connected to.
  • Unlike proxy servers, VPN services are capable of making web browsing completely anonymous and secure as long as they are active.
  • Most VPN services offer a free trial period, after which you need to take out a low-cost monthly subscription (even cheaper annual plans are often available).

Step 2. Sign up for the VPN service of your choice

Most VPN network operators require you to create an account in order to access their infrastructure and have the information necessary to take advantage of the services offered (such as the address of the server to connect to, username and password).

If the VPN service you have selected uses a network protocol other than the default, you will also be provided with all the necessary configuration settings

Method 4 of 4: Use a Smartphone as a Hotspot

Step 1. Verify that your carrier allows data connection tethering

The technical term "tethering" refers to the ability to share the data connection of a smartphone or tablet via Wi-Fi connectivity and to allow another device, such as a computer, to access the internet. It should be noted that not all cellular network operators offer this functionality. However, in many cases it is enough to contact support to be able to enable it (while in others it is necessary to purchase the relative option of the tariff plan).

The easiest way to find out if your smartphone allows tethering is to contact your carrier's customer service for information

Step 2. Disable the device's Wi-Fi connection

Follow these simple instructions:

  • iPhone - launch the app Settings clicking the icon

    Iphonesettingsappicon
    Iphonesettingsappicon

    choose the item Wifi, then turn on the green slider

Step 3. Connect the smartphone to the computer using the supplied cable (it is the same one you use to recharge the battery)

The USB 3.0 connector (rectangular in shape) at one end of the connecting cable plugs into a free USB port on your computer. This is the end of the cable that normally connects to the device's charger.

If you're using a Mac with a USB-C port (also called Thunderbolt 3), you'll need to purchase a USB 3.0 to USB-C adapter in order to connect

Step 4. Insert the connector on the other end of the cable into the relevant communication port on your smartphone

The latter is normally positioned in the lower part of the device both in the case of an iPhone and an Android smartphone.

  • iPhone - launch the app Settings by clicking the following icon

    Iphonesettingsappicon
    Iphonesettingsappicon

    touch the item Personal hotspot, then turn on the white slider

Step 6. Select your smartphone as the internet connection

In most cases, your computer's operating system will automatically set your mobile device connection as the default connection to the web rather than using the Ethernet or Wi-Fi connection. If not, select the network connection icon characterized by this symbol

Windowswifi

(on Windows systems) or from this

Macwifi

(on Mac) and choose the name of your smartphone from the list that appears.

Unlike tethering via Wi-Fi connection, in this case you will not need to enter the password (visible on the service configuration page) to connect

Step 7. Browse the web freely

Since you are using a cellular data connection and not the local LAN on which the restrictions are active, you will be able to access as many websites as you want without any restrictions.

However, remember that tethering can consume a large amount of data traffic in your tariff plan, which means that you may be charged additional costs if downloading large files or viewing streaming content exceeds the traffic threshold foreseen in the your subscription

Advice

  • If you have the possibility to install a program on the computer from which you want to access a blocked website, you can install the TeamViewer software and use it to remotely connect to your home computer from which you can then access any website you want without any limitations (in this case you will have to install TeamViewer on the latter machine as well). Although the browsing speed will be much slower than normal, this method allows you to access any web page using the Wi-Fi connection in your home and the browser installed on your computer.
  • In some cases, downloading files from the internet is blocked at the system level. This means that with your computer you will not be able to download some types of files from the web. In this case, using a proxy server will not allow you to solve the problem.
  • In some cases, using the "https" network protocol instead of "http" within URLs (for example "https://www.web_site_address.com") is sufficient to access a blocked website. It should be noted that not all web services support a secure connection (guaranteed by the "https" protocol) and some access control programs are able to block these connections as well.

Warnings

  • In some countries of the world (for example the United Kingdom or Singapore), circumventing the active access restrictions on a network is considered a crime that can also result in a prison sentence.
  • Many companies and educational facilities keep track of all the data that transits on their local networks. This means that the IT department of the infrastructure you are in is able to trace all the activities you did while connected to the LAN, so pay close attention to the websites you visit.
  • In some cases the computer networks of school facilities are constantly monitored, which means that their administrators know at all times what you are viewing on your computer. In these situations it is useless to bypass the restrictions because the control technicians will immediately close your work session as soon as they realize that you have accessed prohibited content.
