Windows Firewall Blocking IP Primer Tutorial

Windows Firewall Blocking IP Primer Tutorial

A firewall 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).

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).

This kind of control can perhaps protect the computer network “behind” the firewall from some sort of scamming operation.

This would be of pretty obvious interest to system administrators and network administrators charged with protecting the integrity of their network arrangements.

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 …

1. get to a Windows Command Line prompt … and … type …
2. firewall.cpl

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).

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 software called Internet Security 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.

So please take a look at our slideshow showing you the blocking of our mythical 48.xx.xxx.xx IP address using Windows Firewall.
