Here’s where the firewall blocks the website if it exists on the network, because the firewall operates at the IP layer, and monitors each data packet using a “wall of code” to block your device from the web.įirewalls guard the computer’s entry point where information is exchanged between your device and the internet, so it monitors either side of the connection, and decides what goes through and what gets blocked. Next, the website’s name is identified as an IP address, and the TCP packet moves to an IP layer for the routing process.ĭepending on the IP address and routing tables, the layer determines which website server the request will be sent to. Whenever a computer wants to access a particular web page, it creates an HTTP request, which is enclosed in a TCP packet.
This is the first step in understanding why you can’t access your favorite websites, and how the tips we’ll share later in this post can help you bypass the firewall to view the sites you want.
