In addition to disabling or enabling the Windows Firewall, you can customize the rules to allow or block specific network traffic based on your requirements. This allows you to have more granular control over the communication between your server and the outside world.
You can create custom firewall rules through the Windows Firewall with Advanced Security interface or by using PowerShell commands. These rules can define various parameters, such as specific protocols, ports, IP addresses, and more.
Custom firewall rules can help you tailor the server’s network access to your specific needs, promoting both security and flexibility.
Example: Creating a Firewall Rule in PowerShell
Here’s an example of how you can create a custom firewall rule using PowerShell:
| Command | Description |
| New-NetFirewallRule -DisplayName «Allow HTTP Traffic» -Direction Inbound -Protocol TCP -LocalPort 80 -Action Allow | This command creates a new inbound firewall rule that allows TCP traffic on port 80 (HTTP). |
Using PowerShell, you can create highly specific firewall rules to meet your server’s unique requirements.
2. Using Group Policy to Manage Firewall Settings
In an enterprise environment with multiple Windows Server 2019 systems, it may be more efficient to manage firewall settings using Group Policy. Group Policy allows central management of firewall rules across multiple servers, ensuring consistency and easy deployment of configurations.

Во все современные версии Windows встроен брандмауэр Windows Defender Firewall. Это встроенный программный межсетевой экран, который защищает Windows от несанкционированного внешнего доступа к компьютеру и запущенным на нем службам. По умолчанию брандмауэр Windows включен и защищает все сетевые интерфейсы компьютера. Брандмауэр блокирует все входящие подключения и разрешает все исходящие.
Содержание:
- Отключить/включить брандмауэр из панели управления Windows
- Отключить Windows Firewall через GPO
- Как отключить или включить брандмауэр Windows с помощью PowerShell?
В подавляющем большинстве случае Windows Firewall должен быть включен. Если вам нужно разрешить доступ к компьютеру для определенной службы или IP адреса, просто создайте разрешающее правило. Однако в некоторых ситуациях администратору нужно полностью отключить Windows Defender Firewall для проверки сетевых подключений. В этой статье мы покажем несколько способов, как отключить и включить встроенный брандмауэр Windows.
Отключить/включить брандмауэр из панели управления Windows
В современных версиях Windows 10 и 11 для управления брандмауэром используется панель Безопасность Windows (Windows Security).
Если панель Windows Security не открывается или повреждена, вы можете восстановить ее.
- Перейдите в меню Параметры (Settings -> Update & Security -> Windows Security) или выполните команду
windowsdefender://network/
; - Выберите раздел Firewall and network protection;
- По очереди щелкните по каждому из трех сетевых профилей (Domain, Private и Public) и отключите Microsoft Defender Firewall;
,
- Подтвердите отключение в окне User Account Control.
В Windows для каждого сетевого подключения используется один из трех сетевых профилей:
- Domain – применяется для компьютеров, которые добавлены в домен AD
- Private – для небольших офисных LAN, рабочих групп и домашней сети
- Public – для общественных сетей (кафе, аэропорты)
В зависимости от типа сети к сетевому интерфейсу применяются различные правила брандмауэра и настройки обнаружения Windows в сетевом окружении. Вы можете изменить профиль сети подключения как описано тут.
В предыдущих версиях Windows и в Windows Server 2012R2/2016/2019 можно отключить брандмауэр через классическую панель управления «Windows Firewall with Advanced Security«:
- Откройте консоль
firewall.cpl
; - Щелкните по Turn Windows Defender Firewall on or off;
- Отключите Windows Defender firewall для всех типов сетей.
Если на компьютере есть несколько сетевых интерфейсов, вы можете отключить файервол только для некоторых из них.
- Нажмите кнопку Advanced Settings -> Windows Defender Firewall properties;
- В настройках каждого сетевого профиля есть раздел Protected network connections. Нажмите кнопку Customize;
- Снимите галки с тех сетевых интерфейсов, для которых нужно отключить брандмауэр.
- Аналогичным образом отключите защиту сетевых интерфейсов брандмуэром в настройках других сетевых профилей.
Когда вы отключаете брандмауэр, в трее начнет отображаться соответствующее уведомление.
Чтобы скрыть это всплывающее уведомление, добавьте следующий параметр реестра:
reg add "HKLM\Software\Microsoft\Windows Defender Security Center\Notifications" /v "DisableNotifications" /t REG_DWORD /d "1" /f
Обратите внимание, что в Windows есть отдельная системная служба Windows Defender Firewall (
mpssvc
). Если вы отключите или приостановите эту службу, это не отключит брандмауэр до тех пор, пока вы сами не отключите защиту для сетевых профилей.
Однако через остановку служб вы можете отключить встроенный антивирус Защитник Windows.
Отключить Windows Firewall через GPO
Вы можете отключить Windows Firewall с помощью групповых политик.
На отдельном компьютере нужно использовать консоль редактора локальной групповой политики (
gpedit,msc
), а в доменной среде нужно создать новую GPO с помощью консоли управления GPMC.
- Откройте GPO и перейдите в раздел Computer Configuration -> Administrative Templates -> Network -> Network Connections -> Windows Firewall -> Domain Profile.
- Откройте параметр “Windows Firewall: Protect all network connections” и измените значение на Disabled;
- Аналогичным образом измените параметр в секции Standard Profile;
- Обновите настройки GPO на компьютере и проверьте, что брандмауэр для доменного профиля отключен;
- Если компьютер будет подключен к сети, отличной от доменной, Windows Firewall будет защищать такое подключение.
- Если вы хотите отключить брандмауэр для всех сетевых профилей, перейдите в раздел GPO Computer Configuration -> Windows Settings -> Security Settings -> Windows Firewall with Advanced Security. Отключите файервол на вкладках всех трех сетевых профилей.
После того, как вы отключили Windows Firewall через GPO, пользователь не сможет включить его вручную через панель управления.
Как отключить или включить брандмауэр Windows с помощью PowerShell?
Для управления Windows Firewall из командной строки можно использовать PowerShell.
Проверьте, что брандмауэр включен для всех трех сетевых профилей:
Get-NetFirewallProfile | Format-Table Name, Enabled
Можно отключить брандмауэр только для одного сетевого профиля:
Set-NetFirewallProfile -Profile Domain -Enabled False
Или отключить firewall сразу для всех сетевых профилей:
Set-NetFirewallProfile -Profile Domain, Public, Private -Enabled False
Чтобы включить Windows Defender, выполните команду:
Set-NetFirewallProfile -Profile Domain, Public, Private -Enabled True
Вы можете отключить защиту брандмауэра для конкретного сетевого подключения. Чтобы узнать имя сетевого подключения, выведите их список:
Get-NetAdapter
Теперь можно отключить файервол для выбранного интерфейса:
Set-NetFirewallProfile -Profile Domain, Public, Private -DisabledInterfaceAliases "My_Internal_NIC1"
Вывести список сетевых адаптеров, которые исключены из файервола:
Get-NetFirewallProfile | select Name,Enabled,DisabledInterfaceAliases
Очистить список исключений:
Set-NetFirewallProfile -Profile Domain,Public,Private -DisabledInterfaceAliases @()
