12.7 Service Group
This section describes Security > Service Group page.
12.7.1 Introduction to Service Group
The Device provides five service types including general service, URL, Keyword, DNS
and MAC address for the service group. Then the service groups can be used to match
the protocol type (TCP, UDP or ICMP), port number, content, source MAC address of
packets that are received by the Device. For each service type, it allows you to define new
services, or select existing services or service groups, and then add them to the service
group. A service group can contain up to ten service members. A member may be a
service or service group. And a service group may contain services only, or service groups
only, or both.
If you want to create an access control rule in the Security > Firewall page, you can
create a service group in this page firstly, and then reference it in the access control rule.
Using service groups can facilitate the configuration of access control rules. For example,
you can add telnet, pop3 and http services into a service group, and then create one rule
by using the service group to control the access to these services. Else, you need to
create multiple access control rules for the access to these services, one rule per service.
Similarly, you also can reference a service group whose Service Type is General Service
in a rule limit rule in the QoS > Rate Limit Rule page.
