Firewall rule for IP addresses

You can use the Connection Blocking window to configure the firewall for zones in the network to which your Mac is connected. You can configure the zone access settings to specify IP addresses to which you want to allow or block connections.

The Trust Zone in the View pane shows the IP addresses to or from which you allowed access attempts for a network location. The Block Zone in the View pane shows the IP address to or from which you blocked access attempts of a network location.

You can perform the following activities for a zone from the Connection Blocking window:

  • Configure the access settings for an IP address

  • Edit the access settings for an IP address

  • Remove the access settings for an IP address

Thank you!
