Disable windows firewall from cmd

Windows firewall can be enabled/disabled from command line using netsh command.

Windows 10 / Windows 8/ Windows 7 / Server 2008 /Vista:

Let’s see the syntax of netsh advfirewall to configure firewall on these Windows versions.  Firewall settings are different for each of the 3 networks(Domain, private, public). So based on which network firewall you want to enable/disable, the command would vary.

You can turn on firewall for the current network profile(does not matter if it’s domain/private/public network) using the below command.

netsh advfirewall set currentprofile state on

Turn off firewall for the current profile:

netsh advfirewall set  currentprofile state off

These commands should be run from an elevated administrator command prompt. Otherwise you would get the below error.

C:\>netsh advfirewall set  currentprofile state on
The requested operation requires elevation (Run as administrator).

To enable/disable firewall for a specific network profile, you can use the below commands.

Domain network

Turn on Domain network firewall:

netsh advfirewall set domainprofile state on

Turn off domain network firewall:

netsh advfirewall set domainprofile state off

Private network

Turn on private network firewall:

netsh advfirewall set privateprofile state on

Turn off private network firewall:

netsh advfirewall set privateprofile state off

Public network

Turn on public network firewall:

netsh advfirewall set publicprofile state on

Turn off public network firewall:

netsh advfirewall set publicprofile state off

Configure for all networks

Turn on firewall for all networks

netsh advfirewall set allprofiles state on

Turn off firewall for all networks

netsh advfirewall set  allprofiles state off

Older Windows versions – XP / Server 2003:

Below is the command to turn on firewall.

netsh firewall set opmode mode=ENABLE

The command to turn off firewall is:

netsh firewall set opmode mode=DISABLE

Administrator privileges are required to configure firewall so above command can be run only from admin accounts.

netsh firewall is deprecated in new versions.

In Windows 10/ 8 / 7 / Vista/ Server 2008, ‘netsh firewall‘ command prints message like below.

c:\>netsh firewall set opmode mode=ENABLE
IMPORTANT: "netsh firewall" is deprecated;
use "netsh advfirewall firewall" instead. Though the command still works,
 it's preferable to use the new set of commands provided with netsh command.

How to turn off firewall in Windows 7

Firewall is a tricky thing in Windows. It restricts your downloads at times, stops you from remotely connecting to a PC and blocks applications from running, which is quite irritating. But so far this is a top-notch security feature provided by Windows if you know how to use it right. You can configure your firewall to block particular applications from using the Internet and securing your local data.

Block applications from accessing the Internet with GUI is easy. simply go to the Start menu and search for Firewall & Network protection. From the dialogue box, click on Domain Network and turn the Firewall Off. Likewise, you have to turn off the firewall for Private Network and Public Network. In case you need to turn off the firewall only for the Internet, turn off the Firewall only for Public Network.

Disable Windows Firewall With Command Line

However, if you are like me who prefer to disable Windows firewall with the command line, here’s a quick way to do it on Windows 10 and 7.

Open up the command prompt. Go to the Start menu, type Command Prompt. Right click on it and select Run as Administrator. This command to disable Firewall needs elevated permissions, so it needs to be run as an administrator.

On the command prompt, Type

netsh advfirewall set allprofiles state off

Картинка с сайта: techwiser.com

This will turn off the firewall for all 3 networks. To turn it back on, replace off with on.

netsh advfirewall set allprofiles state on

Much like the terminal in macOS and Linux, Windows cmd also lets you move through your last used commands using the up and down arrows on your keyboard. So, if you wanted to previous last command you ran, just hit the up arrow once, edit the command (change off to on) and hit Enter.

Block Any App in the firewall (Command Line)

To block any app in the firewall, we first need to understand what is the inbound and the outbound rule. Inbound rules are defined to either block/allow the app from receiving data on your computer. Outbound rules are defined to either block/allow the application to send data from your computer.

To block any in Firewall using GUI is easy. All you have to do is go to the Firewall & Network Protection.

Click Advanced Settings and go to the Outbound rules tab. Click on New Rule on the right-hand side of the window. Select Rule Type as Program from the pop-up. Click on Next and further steps like specifying program path are self-explanatory.

However, doing the same with the command prompt is not that intuitive. First, you need to decide whether you need to block the app from receiving or sending data from the Internet. Say, you want to block Chrome app from accessing the Internet.

Next, we need to find the location of the .exe file in our system. Usually, it should be in C:\\Program Files, unless you have defined it manually.

Go to the .exe file and copy the path name. In my case for google chrome, the path would be :

C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

Once you have the file location, all you have to do is open Command Prompt with administrator privilege and type the following command :

netsh advfirewall firewall add rule name="Chrome block" program="C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" dir=out action=block profile=public

Now when I open chrome, internet access is disabled.

Block Any App in the Firewall with its Port Number

In case you want to block the app by port number. First, you have to identify the port number. To do that, go to Start menu and type Resource Monitor. Right click on it and select Run as Administrator.

Once the dialogue box opens, go to the Network tab and expand the Listening Ports section by clicking on it.

Once you have the port number use the following command to block that particular port.

netsh advfirewall firewall add rule name="Chrome block" localport=443 protocol=tcp dir=out action=block profile=public

Картинка с сайта: techwiser.com

If you are not sure about the exact port number you can also choose to block a range of ports by specifying port=1000-2000.

To delete this outbound rule, type the below give command with the name of the rule you have specified earlier.

This should fix things and Chrome should be able to access the Internet.

Wrapping Up

These methods enable you to block any particular application from accessing the Internet. This can be used against fishy apps to protect your data from being sent over to private networks or the Internet. If you have any problems with the step, you can comment the error and I can help you out with the solution.

Understanding Windows Firewall

What is Windows Firewall?

Windows Firewall is a critical security feature integrated into the Microsoft Windows operating system. Its primary function is to monitor and control incoming and outgoing network traffic based on predefined security rules. By acting as a barrier between your computer and potential threats from external networks, Windows Firewall helps protect your system from unauthorized access, malware, and various cyber threats.

How Does Windows Firewall Work?

Windows Firewall operates by analyzing data packets attempting to enter or leave your device. It compares these packets against a series of rules to determine whether the traffic is safe or harmful. Essentially, it allows or denies packets based on IP addresses, ports, and protocols—ensuring that only trusted communication can occur. This mechanism is vital for maintaining the security of your computer, particularly when connected to public or untrusted networks.

Reasons to Disable Windows Firewall

Common Situations

There are legitimate reasons to temporarily disable firewall cmd. Common scenarios include:

• Troubleshooting network issues: Sometimes, connectivity problems can arise due to firewall configurations that block certain applications or services.
• Running specific applications: Some programs require open ports or unrestricted access to function correctly, necessitating a temporary firewall shutdown.

Risks of Disabling the Firewall

While disabling the firewall might seem convenient, it presents considerable risks. The most significant danger is the increased vulnerability to malware and unauthorized access. Any threats that bypass the firewall during this period could compromise your system’s integrity. For safe practices, it is always advisable to:

• Re-enable the firewall as soon as possible.
• Limit your exposure to the internet or untrusted networks while the firewall is off.
• Consider using alternative security measures, like antivirus software or enabling specific rules rather than a complete shutdown.

How to Disable Windows Firewall via CMD

Opening Command Prompt

To disable the firewall, you first need to open the Command Prompt with administrative privileges. Follow these steps:

1. Press: `Windows + X`
2. Select: «Windows Terminal (Admin)» or «Command Prompt (Admin)»

Doing so ensures that you have the necessary permissions to modify firewall settings.

Disabling Firewall for Public Profiles

To disable the firewall specifically for public networks, enter the following command in the Command Prompt:

netsh advfirewall set publicprofile state off

This command disables the firewall for public profiles, suitable for scenarios like connecting to public Wi-Fi hotspots. However, always remember that disabling the firewall in public spaces exposes your system to various threats, including unauthorized access and malicious attacks.

Disabling Firewall for Private Profiles

If you need to disable the firewall for private networks, such as your home network, use this command:

netsh advfirewall set privateprofile state off

Disabling the firewall in a trusted environment might momentarily help with issues like file sharing or gaming but should not be done indiscriminately. Always ensure to re-enable it once your task is complete.

Disabling Firewall for All Profiles

To disable the firewall for all network profiles simultaneously, execute:

netsh advfirewall set allprofiles state off

This command turns off the firewall universally, which can be useful but should be approached with caution. You expose your machine to potential risks from all networks without any protective barriers.
