6 Ways to Unblock Websites From Behind a Firewall

Georgina Torbet Updated 22-08-2019

Sometimes you’ll go to visit a site on the internet and find that it’s blocked. You won’t be able to access the site, even though your internet connection is working.


You can check whether the site is working using a checking tool which will tell you if the site’s servers are down. If not, the site could be blocked. If a site you want to visit is blocked, here’s how to unblock websites.

Why Do Sites Get Blocked?

Unblock websites from behind a firewall

There are a number of reasons you might see an error saying “This webpage has been blocked!” The site could be restricted so that it is only available in certain regions. Or the network you are connected to might have a firewall which puts limitations on which sites you can visit. You can check a site’s status using a tool like Down For Everyone Or Just Me.

You may need to unblock sites if you run into problems with automatic spam detection software. Many sites will block access to ranges of IP addresses if they believe them to be the source of spam requests. But sometimes innocent users can get caught up by these filters even if they’re not doing anything wrong.

How to Unblock Websites

To unblock websites from behind a firewall, you have several options. You can try switching to a different network or restarting your modem. Or you can visit a site’s IP address instead of its URL. If just you need to view the page, you can use the Google cache. And if you have access to a VPN or proxy server, you can use this to access the site. Finally, you can try unblocking the site by using the Tor browser.


1. By Switching From Wi-Fi to Mobile Data

Sometimes you’ll find a web page blocked due to restrictions such as a firewall on Wi-Fi networks. If you’re connected to Wi-Fi at school or at work, for example, the network administrator may restrict which sites can be accessed. Sites which are considered inappropriate might be blocked, as might those that require a lot of bandwidth, like YouTube.

If you find a firewall blocking websites, the simplest way to unblock a site is to disconnect from the Wi-Fi network and use another way to access the internet. If you’re on your phone, you can use your mobile data to try and access the site instead. If you can access the site using 3G but not with Wi-Fi, you know that the problem is with restrictions on the Wi-Fi network.

2. By Visiting the Site’s IP Address Directly

If you don’t have the option of using mobile data, you can unblock sites by bypassing the URL. The way domain names work is that when you type one into your browser, such as, your browser is directed to a server. That server sends over text, images, or anything else your browser needs to load the site. If the site is blocked when you type in the URL, you can attempt to access it by going straight to the server’s IP address instead.

This works as sometimes blocks only apply to domain names, such as If you are able to go directly to the server, you can still use the site as normal.


To try this you’ll first need to find out the IP address of the site you want to visit. Go to a page like IPVoid’s Find Website IP tool and enter the domain you want to know the IP address for, such as Then hit the Find Website IP button.

This will bring up an IP address in the lower text box. In the case of, the IP address is

Now copy this IP address and enter it into your browser. You should be taken to the site you’re looking for, and you may be able to access it even if the domain is blocked.

3. By Viewing a Cached Version of the Site

Unblock websites from behind a firewall - Google Cache


If a site is down but you still need to access it, you can try using the cache. This is ideal if the site isn’t updated very often and you just need some information from it.

The cache is an older version of the website which Google keeps a copy of as a backup. It can’t show you pages that you need to be logged in for, such as Facebook content. But it can show you older versions of simple text-based sites that don’t require a login.

To use the Google Cache, perform a search for the site you want. You can do this by entering in, for example.

In the Google search results, you’ll see the title of the website, then below that a snippet of the content on the site, then below that the site’s URL. Next to the URL is a link that says Cached. Click the to view the Google Cache version of the site.


Alternatively, you could also try accessing a different version of the site, such as the mobile version or a version in a different language or for a different region. You might find that only one version of the site has been blocked.

4. By Restarting Your Modem

Sometimes your modem will assign you what is called a dynamic IP address. That means that whenever you connect to the internet, you’ll be assigned a temporary IP address to use for that session.

If a website has blocked your IP address, you can get around this by getting a new IP address. The easiest way to do this is to restart your modem and you’ll have a new IP address once your modem reboots.

However, if your ISP assigns you a static IP address, which is more common, then your IP address will remain the same no matter how many times you restart your modem.

5. How to Open Blocked Websites by Proxy or VPN

If you have a static IP address, there is another way to change it. You can use a VPN 11 Reasons Why You Need a VPN and What It Is Virtual private networks can protect your privacy. We explain what exactly they do and why you should use a VPN. Read More or a proxy server to access blocked sites by masking your real IP address behind a fake one.

These two tools work slightly differently, but for the purposes of unblocking a website they are the same. You start your proxy or your VPN, and the service assigns you a new IP address. Then, when you send a request across the internet, for example to load a particular page, that request appears to come from the new IP address.

This means you can use a proxy server to open blocked sites. If a site is blocked in your geographical region, as you can connect to a proxy or VPN server which is located in another country.

6. How to Unblock a Website Using the Tor Browser

If all of these methods fail, you can try using the Tor browser 7 Tips for Using the Tor Browser Safely Thinking about trying the Tor browser to start browsing the web safely? Learn these Tor browser dos and don'ts before you start. Read More . Tor is designed to hide its users’ locations, so they can browse the internet without censorship.

Similar to a VPN or proxy, when you use Tor your real IP address is hidden behind a new IP address assigned to you. That means you can use Tor to access websites even if they are blocked on other browsers.

The downside to using Tor is that it can be slow and it is not compatible with all devices such as iOS devices. But if you’re on desktop or Android and you’re looking for a solution that will let you access text sites from anywhere, it’s worth trying.

Use These Tips to Unblock Websites and Browse Freely

Just because a site is blocked from your browser doesn’t mean it’s impossible for you to access it. Using these methods, you’ll be able to access many sites even if they are blocked at first.

    This was probably the first trick you knew as a university kid to access all those blocked social networking sites. Proxy websites acts as an intermediary between the blocked site and you. Essentially what it does is mask from your ISP that you are accessing the blocked site when you are connected to the proxy’s server instead of the website’s server.

    I'm having trouble with a website that's doing this, but none of this has worked so far. It seems to know when you're using a proxy, and blocks you out. There's something about the phone's ip I can temporarily change that lets me in, but as soon as I connect to our WiFi, it blocks me again. And even if I change the ip for the WiFi, it shuts of the Internet connection. Any idea what might be going on?

    These tips sounds great but I already choose an application named IP Privacy and I am more the satisfied with it.

    Thanks for the article, I will be testing this out @ my library, since they have to have such a good firewall.

    I can hardly bypass any of it's filters no matter what I try

    Oh, Google Translate doesn't work for me @ the library, tried translating a web page but "proxy avoidence" was filtered

    Thanks Albert - It's great that you like my name. :P It will be easy for you to remember me then.

    KallAngo - Google Translator is only good, like you said if you need to access the site that its a different language as it kind of acts like a proxy. It's just a pitty that you can't translate English to English, otherwise you could be able to access anything on the internet.

    One thing that I use and it works fine too, is to use google translator with a blocked address...

    Access google translator ans use it to translate the site you want to access to your own language.

    I use this some times and works fine to unblock some web pages...
