Specify the firewall list of domains or hosts where the firewall should not be used. For example, if you do not want to FTP to the firewall for hosts on your own probe.net domain, set this field to probe.net. To specify a list of domains or host names, separate them with a comma.
A special token localdomain is used for unqualified host names, so be sure to include that in your list if you want hosts without explicit domain names to avoid the firewall.
