Network Zones

Comodo Firewall allows you to define 'Network Zones' and to specify the access privileges of these zones. A 'Network Zone' can consist of an individual machine (including a single home computer connected to Internet) or a network of thousands of machines to which access can be granted or denied.

Background Note: A computer network is a connection between computers through a cable or some type of wireless connection. It enables users to share information and devices between computers and other users within the network. Obviously, there are certain computer networks where you need to grant access to, including your home or work network. Conversely, there may be other networks where you want to restrict communication with - or even block entirely.

To access the Network Zones interface

Click 'Network Zones' tab from Firewall Tasks > Network Security Policy interface.

Note 1: Adding a zone to this area does not, in itself, define any permission levels or access rights to the zone. This area allows to define the zones so you can quickly assign such permissions in other areas of the firewall.

Note 2: A network zone can be designated as 'Trusted' and allowed access by using the 'Stealth Ports Wizard'. (An example would be your home computer or network)

Note 3: A network zone can be designated as 'Blocked' and denied access by using the 'Blocked Zones' interface. (An example would be a known spyware site)

Note 4: An application can be assigned specific access rights to and from a network zone when defining an Application Rule. Similarly, a custom Global Rule can be assigned to a network zone to all activity from a zone.

Note 5: By default, Comodo Firewall automatically detects any new networks (LAN, Wireless etc). This can be disabled in the Firewall Behavior Settings > General Settings area of the application.
