Microsoft has been offering a built-in firewall for all the Windows users since the days of Windows XP. Previously knows just as Windows Firewall, Microsoft has now renamed it into Windows Defender Firewall in the newer versions of Windows 10. Even though you can configure the rules and settings of this firewall through the very detailed interface offered by Windows Firewall itself (which can be accessed by entering wf.msc in the Run dialog), you can configure various firewall rules easily through an open-source program called simplewall.
simplewall is available as a portable program which makes it very convenient for you to configure the firewall rules of any Windows computer. The program is very small in size but don’t be fooled by less than 1 MB of program file – it provides you with all the tools for complete control of Windows Defender Firewall.
As you launch it, it will display two lists allowed and blocked. In the blocked list, you will see all the programs, processes and services banned from accessing the internet and in the allowed list you will see the ones that are allowed to access the internet. In order to add new programs to the list, just right-click on any of the lists (allowed or blocked) and you will find programs, files, packages and services that you can add. Depending on the list you add this new program, it will be blocked or allowed to access the internet. You can switch the programs from one list to another later on. You must click on the Enable Filtering button after making all the changes. What can be simpler than this?
In the settings of simplewall, you can access more settings and rules of Windows Defender Firewall. You can see the firewall rules of three kinds – system rules, blocklist rules and the user created rules, you can customize the color scheme for the interface of simplewall among many other things.
With the simplewall tool you can define your own rules for the Windows Firewall in a much quicker and easier way. Why Microsoft cannot create such smarter software remains a mystery.
