Services, Bandwidth Profiles, and QoS Profiles
When you create inbound and outbound firewall rules, you use firewall objects such as
services, QoS profiles, bandwidth profiles, and schedules to narrow down the firewall rules:
services, QoS profiles, bandwidth profiles, and schedules to narrow down the firewall rules:
•
Services. A service narrows down the firewall rule to an application and a port number.

Bandwidth profiles. A bandwidth profile allocates and limits traffic bandwidth for the
LAN users to which an IPv4 firewall rule is applied. For information about creating

and game hosts serve data about players’ moves. When a computer on the Internet sends a
request for service to a server computer, the requested service is identified by a service or

packets. For example, a packet that is sent with destination port number 80 is an HTTP (web
server) request.
