Open the ‘Firewall’ section of a Windows profile > Click the ‘Network Zones’ tab.

  • A network zone is a list of addresses or hostnames that you create in the ‘Firewall’ section of a Windows profile. You can add multiple addresses and hosts to each named zone.
     
  • Once created, you can specify the zone as the target of a firewall ruleset. Firewall rulesets let you control traffic to and from the network zone at a very granular level.
     
  • You can also block a zone completely in the ‘Network Zones’ tab.
     
  • This article explains how to create and configure a network zone in a Windows profile.

Process in brief

  • Login to ITarian
     
  • Click 'Applications' > 'Endpoint Manager'
     
  • Click ‘Configuration Templates’ > ‘Profiles’
     
  • Open the Windows profile applied to your target devices
     
    • Open the 'Firewall' tab if it has already been added to the profile

      OR
       
    • Click 'Add Profile Section' > 'Firewall' if it hasn't yet been added:
       
  • Click the 'Network Zones' tab
     
  • Configure General network settings, Network Zones and Blocked Zones as required.
     
  • Click 'Save' for your settings to take effect

Process in detail:

  • Login to ITarian
     
  • Click 'Applications' > 'Endpoint Manager'
  • Click ‘Configuration Templates’ > ‘Profiles’
     
  • Open the Windows profile applied to your target devices
     
    • Open the 'Firewall' tab if it has already been added to the profile

      OR
       
    • Click 'Add Profile Section' > 'Firewall' if it hasn't yet been added:
       
  • Open the 'Network Zones' tab:



 

General Network Settings:

The two settings at the top determine how Comodo Client Security (CCS) should handle new networks:

  • Enable automatic detection of private networks - The CCS firewall monitors attempted connections to any new wired or wireless networks. This is enabled by default. The next settings let you choose how the firewall behaves if it detects a new network.
     
  • Do Not show popup alerts - By default, CCS shows the following notification to users when it detects a new network:


     
    • The user is asked to specify their location so CCS can implement the appropriate rules for the network.
       
    • Enable ‘Do not show...’ to eliminate these pop-ups. You then need to pick a default location that CCS should always implement:



 

Network Zones

A network zone is a collection of addresses to which you want to control access via the Comodo Client Security firewall.

  • You can specify a zone as the source or destination address in a firewall ruleset
     
  • You can specify a zone as the source or destination address in a global rule
     
  • You can block a zone entirely in the ‘Network Zones’ tab

Click the 'Network Zones' tab to get started:


 

  • Click 'Add' to create a new zone:




     
  • Name -  Create a label for the zone. After saving, the zone name will be available for selection when creating a firewall ruleset/global rule.
     
  • Public network- Public networks are ‘open’ networks that offer very little security. Examples include public WiFi at cafes, airports, libraries and so forth.  Enable this option if you want the CCS firewall to treat this zone as a public network. The firewall will implement the appropriate permissions.
     
  • Click 'Add' to add the computers in the new network zone


     

Select the kind of network address you want to add:


 

You can select any of the following address types:

Any Address - Adds all the IP addresses (0.0.0.0- 255.255.255.255) to the zone.

Host Name- Enter a named host which denotes an address on your network.

IPv4 Range - Includes all the IPv4 addresses between the values you specify in the 'Start Range' and 'End Range' text boxes.

IPv4 Single Address - Enter a single IP address to be added to the zone - e.g. 198.51.100.2.

IPv4 Subnet Mask - A subnet mask allows administrators to divide a network into two or more networks by splitting the host part of an IP address into subnet and host numbers.

  • Enter the IP address and Mask of the network you wish to add to the defined zone.

IPv6 Single Address -Enter a single address to be added to the zone - e.g. 3ffe:1900:4545:3:200:f8ff:fe21:67cf.

  • Enter the IP address and Mask of the network.

IPv6 Subnet Mask - IPv6 networks can be divided into smaller networks called sub-networks (or subnets). An IP address/ Mask is a subnet defined by IP address and mask of the network.

MAC Address - Enter a specific MAC address to be added to the zone.

Exclude – Adds every address to the zone except the ones you specify here.

Click 'OK'  to add the address to the zone. You can add more addresses, and more address types, to the zone by repeating the process above.

Click ‘OK’ in the main zone config window to add your zone to Endpoint Manager.

The zone will be available when you choose 'Network Zone' as the source/destination address in a  firewall rule.
 

Blocked Zones

The 'Blocked Zones' tab lets you completely prevent access to and from zones you do not trust.

Add an existing network zone to be blocked

  • Click 'Add from Network Zone'

    The 'Network Zone' drop-down shows all network zones added to the profile, under the 'Network Zones' tab, as explained above.

  • Choose the zone you wish to block from the 'Network Zone' drop-down and click 'Add'.
     
  • The network zone is added to the blocked zones.
     
  • Repeat the process to add more blocked network zones for the profile

Add a new network zone to be blocked

  • Click 'Add' in the 'Blocked Zones' interface



     
  • Add the address of the network zone to be blocked as explained above.
     
  • Click 'OK' to save the blocked network zone
     
  • Click 'Save' in the Firewall settings pane for your changes to take effect.
