There are various DNS servers all over the world. We need to allow access to a DNS server first. We can't just allow access to our website by making a rule for it. How would you like to type in 73.9.3.1 every time you wanted to see how last year's NBA Finals went? It would not be fun, well it would be but still, you get the point. Without a DNS server, you would need to know the exact IP address to type in. So when I type in my address bar, a DNS server then resolves that URL to an IP address for me. If one is found, it then automatically routes you to the right IP address which is where the web content is served. Your web requests are routed to a DNS server which then searches its list to find a match. You are still able to get to the server that is hosting the website. When you type in the URL of a website, that URL is not the actual server name (it better not be anyways). Define Alias for Website/IP address you want to block or allowīefore we go any further, we need to talk about how web traffic works.It is only an example of what you can do and how to do it. I am going to show you a little of everything here so you know how it works but don't take this example of exactly what you should do. There are some free lists out there but let's face it, it someone isn't getting paid to do it, what makes you think you are going to be truly protected? Here, you have to rely on lists (the best and most up to date lists charge a subscription fee). With this, you allow all web traffic by default and only block access to websites you explicitly deny. ![]() You may think this is easy but you will realize in our example what a pain it can be. This means you block all traffic by default and only allow users to access certain sites that you explicitly allow.It is time to start thinking about how much effort you are willing to put into this firewall and how strict you want to be.
