User Group
This section describes the
User Management > User Group
page.
8.5.1 Introduction to User Group
An User Group can contain up to ten address members. A member may be an address
range or User Group. And an User Group may contain address ranges only, or User
Groups only, or both.
If you want to create an access control rule (in the
Firewall
>Access Control
page)
whose destination or source IP addresses are discontinuous, you can create an User
Group for them in this page firstly, and then reference it in the access control rule. When
receiving a packet, if the packet
’s destination or source IP address belongs to the User
Group, the Device will consider that its IP address matches the access control rule. And if
the packet also matches other criteria (protocol type, destination ports, schedule, etc.) of the
access control rule, the Device will consider that the packet matches the access control
rule.
Using User Groups can facilitate the configuration of access control rules. For example, if
some LAN hosts
’ IP addresses are discontinuous, but the hosts have the same privileges
of accessing the Internet, you can create an User Group for these hosts. Then you only
need to create one access control rule by using the User Group to meet the
hosts’
requirements. Else you need to create multiple access control rules for these hosts.
Similarly, you also can reference an User Group in a rule limit rule in the
QoS >
Fixed
Rate Limiting
page.
