Dr.Web Firewall

Dr.Web Firewall protects your mobile device from unauthorized access and prevents leaking of vital data through networks. This component monitors connection attempts and data transfers, and helps you block unwanted or suspicious connections.

Certain aspects of Dr.Web Firewall operation

Dr.Web Firewall is based on the VPN for Android technology, so it does not require root access on the device. However, the VPN for Android technology sets a number of limitations:

Only one app can use VPN at a time. As a result, before enabling VPN, the app prompts you to provide it the corresponding permission. If you give the permission, the app starts using VPN, but it also blocks access to VPN for other apps. Dr.Web Firewall requests the VPN permission the first time you enable the component. It can also request the permission after a device reboot and after VPN requests from other apps. VPN is shared between the apps over time. Dr.Web Firewall can operate only when it gets the full rights to use VPN.

Enabling Dr.Web Firewall can result in inability to connect the device on which Dr.Web Firewall runs to other devices directly using Wi-Fi or a local network. It depends on the device model and the apps which are used to establish a connection between devices.

When Dr.Web Firewall is enabled, you cannot use your device as a Wi-Fi access point.

Dr.Web Firewall uses the VPN for Android technology only to perform its functions, without creating a VPN tunnel, so the traffic is not encrypted.

To enable Dr.Web Firewall

1.On the Dr.Web main screen, select Firewall.

2.Tap the Enable button or use the toggle button in the top-right corner of the screen.

Dr.Web requests the permission to set up a VPN connection. You need to grant the permission in order for Dr.Web Firewall to function.

To enable Firewall after the device boots, open Dr.Web.

On devices with Android 7.0 or later, you can set your OS to automatically enable Dr.Web Firewall after the device boots. To do so:

1.In your device settings, select VPN.

2.Open the Dr.Web Security Space (Dr.Web Security Space Life) network settings.

3.On the Dr.Web Security Space (Dr.Web Security Space Life) screen, enable the Always-on VPN setting.

On devices with Android 8.0 or later, you can block access to the internet after the device boots until the VPN successfully connects. To do so, enable the Block connections without VPN setting.

If another app starts using VPN, Dr.Web Firewall will be disabled. You will see a corresponding notification. Tap this notification to enable Dr.Web Firewall again.

 

If you use a restricted profile (guest profile) on your device, Dr.Web Firewall is disabled.
