Here I have already posted several articles on how to unblock several websites like orkut, facebook bebo or any other in colleges or offices using proxy software and proxy sites. But today this article will be a total turn-around as how you can create a simple firewall to block certain websites at your home being accessed by your child.

This trick does not require any special skill but only a slight modification into the system host file with the sites names included those you want block access keep in mind that this process is totally reversible, if later you want to gain access any particular sites remove from the list. Below is the process to create this simple firewall protection as this can also be used to stop spam sites:

1. Click on start and then Run menu (You can also use Windows Key + r to open the run window)

2. Type notepad C:/Windows/System32/drivers/etc/hosts
as it is the bold letters in the text box (Copy and paste will be the best solution)

3. This will open the notepad editor now type 127.0.0.1 (which is the local host) and give a space then type the name of the site you want to block e.g

127.0.0.1 orkut.com and save the file.

By this way you can add many as site in the list and in case if you want to gain access to any site you have blocked repeat the first two process and then from notepad document remove that particular site.

Hope you have liked this trick very much and I deserves a feedburner’s subscription isn’t so?
