Create Services, QoS Profiles, and Bandwidth Profiles

When you create inbound and outbound firewall rules, you use firewall objects such as 
services, service groups, IP groups (LAN and WAN groups), 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. 

You can also narrow down the firewall rule to a group of services. For information about 
adding services and service groups, see 

on page 152 and 

IP groups. An IP group is a LAN group or a WAN group to which you add individual IP 

addresses. You can narrow down the firewall rule to such an IP group. For information 
about creating IP groups, see 

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 creating QoS 
profiles, see 

Bandwidth 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 

A schedule narrows down the period during which a firewall rule is 

applied. For information about specifying schedules, see 

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.

The service numbers for many common protocols are defined by the Internet Engineering 
Task Force (IETF) and published in RFC 1700, Assigned Numbers. Service numbers for 
other applications are typically chosen from the range 1024 to 65535 by the authors of the 
application.

Although the UTM already holds a list of many service port numbers, you are not limited to 
these choices. Use the Services screen to add additional services and applications to the list 
for use in defining firewall rules. The Services screen shows a list of services that you have 
defined, as shown in
