Example: Filtering Traffic Between Subnets
It is possible to filter traffic to either a specific address or to an entire subnet. In this
example, all traffic between the two subnets is filtered:
❒
10.1.1.0
❒
10.1.2.0
This example also assumes that the network is a Class C network (255.255.255.0).
To filter traffic between both subnets, you must create two access rules.
To create the access rules:
1.
In the
IP Configuration
section of the Web Agent window, click
Access Lists
.
The IP Access List dialog box opens.
2.
Click
Create Extended
