by default.

Services, Bandwidth Profiles, and QoS Profiles
• Add Customized Services
• Create IP Groups
• Create Bandwidth Profiles
• Create Quality of Service Profiles for IPv4 Firewall Rules
• Quality of Service Priorities for IPv6 Firewall Rules
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 service narrows down the firewall rule to an application and a port number.
For information about adding services and IP groups, see Add Customized Services on
page 177 and Create IP Groups on page 179.
• Bandwidth profiles. A bandwidth profile allocates and limits traf
fic bandwidth for the LAN
users to which an IPv4 firewall rule is applied. For information about creating bandwidth
profiles, see Create Bandwidth Profiles on page 181.
