Configuring IP Routing

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. Select Access Lists from the Routing > IP > Configuration
group on the web Agent window. The IP Access List dialog
box opens (Figure9-5).
2. Select Create Extended. The IP Extended Access Rule
Creation dialog box opens (Figure9-7).
3. Enter a number between 100 and 199 in the Access List Name
field to identify your new access control list.
4. Enter a number in the Access Rule Index file to identify the
access rule.
5. Select Filter from the Access Type field pull-down menu.
6. Enter the source address (10.1.2.0) and the source address
wildcard (0.0.0.255), respectively, in the Source Address field.
7. Enter the destination address (10.1.1.0) and the destination
address wildcard (0.0.0.255), respectively, in the Dest Address
field.
8. Enter the following in the TCP/UDP Destination Port field:
— a Min. of 80(HTTP).
— a Max. of 80 (HTTP).
9. Enter the following in the TCP/UDP Source Port field:
— a Min. of 80(HTTP).
— a Max. of 80 (HTTP).
