Windows Firewall Blocking IP Primer Tutorial<\/p><\/div>\n

A firewall<\/a> is a security device, or network security system, designed to protect a secure internal network from other networks, by the means to control the incoming and outgoing network traffic, via a rule set (in a similar way to how some email systems allow the user to write their own rules, to control the flow of emails into their email client mailboxes).<\/p>\n

Today, with our slideshow example, we imagine, on a Windows 7 laptop, that you want to block (or ban) the network traffic from a nominated IP address (or range of IP addresses).<\/p>\n

This kind of control can perhaps protect the computer network “behind” the firewall from some sort of scamming operation.<\/p>\n

This would be of pretty obvious interest to system administrators and network administrators charged with protecting the integrity of their network arrangements.<\/p>\n

The way to access the firewall functionality in Windows has been pretty fluid over the various versions of the Windows operating system, but the one we gravitate towards, as a generic piece of advice, is to …<\/p>\n

    \n
  1. get to a Windows Command Line prompt … and … type …<\/li>\n
  2. firewall.cpl<\/li>\n<\/ol>\n

    The firewall in Windows 7, at least, also appears in Control Panel as “Windows Firewall” … mainly because it would be pretty obtuse to say “Fenestra Firewall” (though it sounds like a good movie).<\/p>\n

    Sometimes the firewall duties for a Windows laptop, for instance, are taken on by the Virus Protection software you have installed, perhaps. For instance, the Norton by Symantec<\/a> software called Internet Security<\/a> offers up its own Windows Firewall as an option for use, that will supercede any Windows Firewall arrangements that come with an install of the Windows operating system.<\/p>\n

    So please take a look at our slideshow<\/a> showing you the blocking of our mythical 48.xx.xxx.xx IP address using Windows Firewall.<\/p>\n
