Firewalls are used to block unwanted access to networks. They protect computers from threats. But sometimes, they block useful websites too. So, can a VPN bypass a firewall? Let’s find out.
What is a VPN?
A VPN stands for Virtual Private Network. It creates a secure connection over the internet. It hides your IP address and encrypts your data. This makes your online activities private.
What is a Firewall?
A firewall is a security system. It monitors and controls incoming and outgoing network traffic. It blocks harmful data from entering your network. Firewalls can be hardware, software, or both.
How Does a VPN Work?
A VPN connects your device to a remote server. All your internet traffic goes through this server. The VPN server encrypts your data. This means no one can see what you are doing online.
How Does a Firewall Work?
A firewall checks data packets. It decides if the data is safe or not. If the data is safe, it lets it through. If not, it blocks it. Firewalls use rules to make these decisions. These rules are set by network administrators.
