8.1.4 Configuration Examples for Access Rule
8.1.4.1 Example 1
-
Only Allow a Group of Users to Access
Certain Services
In this example, we want to allow a group of users (IP address range:
192.168.1.10-192.168.1.20) to access web service, and block them from accessing any
other services.
We need to create three access rules to meet the requirements:
●
Access rule 1: It allows those users to access DNS service. And it is used to ensure
that the domain names can be resolved successfully, thus the users can access web
service properly.
●
Access rule 2: It allows those users to access Web service.
●
Access rule 3: It blocks those users from accessing any Internet services.
Therein, both rule 1 and rule 2 must have a higher priority than rule 3. Otherwise, rule 3
will be matched first. This will make those users unable to access web service.
