Configuring the firewall security level

The firewall can adapt your protection depending on the type of network to which your PC is connected.

The increasing number of laptop computers and the options for using these on a variety of network environments means firewall protection should be able to adapt to the different types of network to which you might connect.

For example, an Internet connection through a wireless network in an airport, requires a different security policy from a connection on a local network.

Even though, by default, the firewall applies a different security level in accordance with the type of network to which you connect, you can change this configuration whenever you want.

To do this, follow these steps:

Click Status in the main menu.
In the Protection section, click Settings.
Select the Firewall option.
In the Networks section, click Settings.
Select a network, if there is more than one, and indicate the name with which you want to identify it. Click Settings.

Note: If you click on Details you can see the name of the network card used for the connection, the IP address, the gateway, the DNS servers, etc.

Specify whether it is a trusted network or a public network.

Trusted network: Trusted networks are local networks (for example, home networks) in which you can share files or printers with other computers on the network. If you select this option, when your PC connects to a local network, the firewall applies a security level that lets you share resources with other computers on the network.
Public network: Public networks are those to which your PC can connect in public places such as airports, universities, cyber cafes, etc. If you select this option, the firewall applies a more restrictive security level to prevent other computers on the network from accessing your shared resources.

Other options:

Enable automatic network mode: The firewall protection will apply different security levels to networks, depending on the type of network in question.
