By default, your firewall prevents inbound access and allows all outbound access.
If you want to allow some inbound access or prevent some outbound access, you
must configure firewall rules. You can choose how and to whom the rules apply
and can specify these settings:
• Services or traffic types (examples: web browsing, VoIP, other standard
services and also custom services that you define)
• Direction of the traffic
• Days of the week and times of day
• Keywords in a domain name or on a URL of a web page
• MAC addresses of devices
