A firewall, or firewall, is designed to control the operation of programs on the network and to protect the operating system and user data from external attacks. There are many programs with similar functions, and they are not always effective. To check the quality of your firewall, use the 2ip Firewall Tester program.
Instructions
Step 1
Search for a link to download the 2ip Firewall Tester utility. Check the downloaded files with an antivirus program and run the application. As a rule, the program needs to be installed on the hard disk of the computer. After that, a shortcut will appear on the desktop, with which you can launch it.
Step 2
The program window is quite simple and contains a message line and two buttons Help and Test. Make sure that your computer has Internet access and click on the Test button. The utility will attempt to communicate with the external server. If the connection is established (which will be reported in red letters), then your firewall is ineffective. It is also worth noting that most of such software is installed by default with an English-language interface. To change to Russian, go to the program settings. Do not forget to save any changes that have been made to the program.
Step 3
If the connection could not be established, and the firewall program prompted for permission for this connection, then the firewall is working. Allow a one-time connection. For a more complex firewall check, rename the 2ip Firewall Tester utility startup file to the name of a program whose Internet access is known to be allowed. For example, Internet Explorer. To do this, name the utility iexplore.exe, run it again and click the Test button. If the connection is established, then your firewall has a fairly low level of protection.
Step 4
If the connection is not established, then your firewall program is performing its functions by five points. You can safely surf the Internet, because your personal computer is reliably protected from various threats. As a rule, such software has flexible settings in the system.
