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. A se
rvice narrows down the firewall rule to an application and a port number.
For information about adding services, see Add Customized Services o
n page 136.
• B
andwidth profiles. A bandwidth profile allocates and limits traffic bandwidth for the LAN
users to which a firewall rule is applied. For information about creating bandwidth profiles,
see Create Bandwidth Profiles on p
age 139.
• QoS profiles.
A Quality of Service (QoS) profile defines the relative priority of an IP
packet for traffic that matches the firewall rule. For information about QoS profiles, see
Preconfigured Quality of Service Profiles on p
age 141.
Note: A schedule narrows down the period during which a firewall rule is
applied. For information about specifying schedules, see
Set a
Schedule to Block or Allow Specific Traffic on page 146.
Add Customized Services
Services are functions performed by server computers at the request of client computers. You
can configure up to 125 custom services.
For example, web servers serve web pages, time servers serve time and date information,
and game hosts serve data about other 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 port number. This number appears as the destination port number in the
transmitted IP packets. For example, a packet that is sent with destination port number 80 is
an HTTP (web server) request.
