Dr.Web Firewall protects your 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 and at every device reboot. It can also request the permission 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 (see Figure 38).
2.Do one of the following:
•Use the toggle button to the right of the Log panel.
•Select Traffic or Log and tap Enable.
By default, Dr.Web Firewall is disabled. Dr.Web requests a permission to set up a VPN connection. You need to grant the permission in order for Dr.Web Firewall to function.
|
If another app gets the rights to use VPN during the operation of Dr.Web Firewall, the component will be disabled. You will be notified on it.
If you use a restricted profile (guest profile) on your device, Dr.Web Firewall is disabled. |
