Dr.Web Firewall

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

Dr.Web Firewall features

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

First, only one application can use VPN at a time. Before enabling VPN, the application prompts you to provide it relevant permission. If you give the permission, the application starts using VPN, but it blocks access to VPN for other applications. Dr.Web Firewall requests VPN permission the first time you enable the component. It can also request the permission after the device reboot and after VPN requests from other applications. VPN is shared among the applications over time. Dr.Web Firewall can operate only when it gets 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 local network. It depends on the device model and applications 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 VPN tunnel, so the traffic is not encrypted.

To enable Dr.Web Firewall

1.On the application main screen, tap the Firewall option.

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

Dr.Web requests a permission to set up a VPN connection. Give the permission, to allow Dr.Web Firewall operating.

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.

When other application starts using VPN, Dr.Web Firewall will be disabled. You will see a corresponding notification. Tap this notification to enable Dr.Web Firewall again.
