What Is a Firewall and How Can a VPN Bypass It?Last Updated by Sarah Barnes on February 06, 2019
Have you ever tried to sign into Twitter or Facebook while you’re at work and been met with an error message on your browser instead?
Everything from Instagram to Pinterest, and even your favorite gambling websites might be out of bounds. Luckily for you, there is a way you can bypass these firewalls.
Firewalls are a network security device that come in the form of software or firmware. They create a barrier between your internal networks and those from the outside world.
Companies, schools, and government institutions put them in place to restrict your access to certain websites they deem inappropriate. Most commonly, they block social media and video streaming platforms. That said, they also block you from accessing pornographic content as well as gambling websites in most cases.
The Great Firewall of China is the Chinese government’s attempt to block a huge variety of foreign websites while also slowing down cross-border internet traffic. The firewall also blocks foreign internet tools, international social media platforms, mobile applications, and websites that the government deems unsavory..
So, with such sophisticated technology in place, how can you access your favorite websites while at work, college, or even abroad? Thankfully, with the right Virtual Private Network (VPN) you can access all your favorite sites and more, completely under the radar.
Using a VPN to Bypass a Firewall
By connecting to a server in a location of your choosing, you will receive a new IP address. This will allow you to trick the government, your Internet Service Provider (ISP), and anyone else snooping around in your online activities, into thinking that you’re in a completely different location. They’ll also hide all your traffic and connection data from anyone who might like to abuse it.
But, there’s a catch. Not all VPN services are the same. Let’s have a closer look.
Choosing the Best VPN to Bypass Firewalls
When choosing a VPN to bypass firewalls, you must consider the following:
1 Security Protocols and Encryptions
To bypass strong firewalls, you’re going to need a VPN with multiple security protocols and various layers of encryptions.
Some to look out for include:
- Layer-2-Tunnel Protocols (L2TP)
- Point-to-Point Tunneling Protocols (PPTP)
- Secure Socket Tunneling Protocol (SSTP)
OpenVPN is the most reliable, safe, and flexible protocol and will stop any firewall from standing in your way. Aside from choosing a service with OpenVPN, make sure it has 256-bit AES encryption as well as DNS and IPv6 leak protection.
2 Repertoire of Servers
When choosing your preferred VPN service, you must ensure the company has a large repertoire of servers because the majority of firewalls block users according to their IP address. Thanks to its blacklist of IP addresses, the firewall knows who it should allow to gain access to websites and who it shouldn’t.
Your VPN needs to provide you with a large number of servers, therefore if you use one and it doesn’t work, you can simply switch to another.
Make sure you check that the company has servers in your preferred countries as well because if you want to watch US Netflix, you’ll need a VPN that has a large selection of servers in the US so you aren’t stopped from watching your favourite shows.
If you plan on using your VPN to access movies, shows, and games, it’s important you choose a service that offers high speeds. Go for a VPN with unlimited bandwidth and no throttling.
One tip is to opt for a VPN that has servers near you, as this could increase your internet speed further.
