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. The IP Extended Access Rule Creation dialog box opens.
3. In the Access List Name field, enter a number between 100 and 199 to identify
your new access control list.
4. In the Access Rule Index field, enter a number to identify the access rule.
