5. From the Access Type pull-down menu, select Filter.
6. In the Source Address field, enter the source address (10.1.2.0) and the source
address wildcard (0.0.0.255), respectively.
7. In the Dest Address field, enter the destination address (10.1.1.0) and the
destination address wildcard (0.0.0.255), respectively.
8. In the TCP/UDP Destination Port field:
• Enter a Min. of 80(HTTP).
• Enter a Max. of 80 (HTTP).
9. In the TCP/UDP Source Port field:
• Enter a Min. of 80(HTTP).
• Enter a Max. of 80 (HTTP).
10. Select TCP Established. A check mark displays in the check box.
11. Click CREATE to save your changes, or CANCEL to restore previous settings.
Once you complete the creation of both access rules, all traffic between subnet 10.1.1.0
and 10.1.2.0 is filtered. Note that traffic between subnet 10.1.1.0 and 10.1.3.0, and
10.1.2.0 and 10.1.3.0 is not filtered. This is because your access rules only filter traffic
between 10.1.1.0 and 10.1.2.0.
Note: To filter traffic to a specific address and not to an entire subnet, you must
specify the destination address of the network node, and use a subnet
wildcard of 255.255.255.255.
To filter all traffic, you must specify a destination address of 0.0.0.0 and a
subnet wildcard of 0.0.0.0. This filters out all traffic. This is useful if you want
to filter all traffic except traffic that matches a previous rule. Ensure that you
do not make this your first rule, since that overrides all subsequent rules.a
Activating Access Lists
You can specify which access lists to activate on the switch by selecting Access Control in
the IP Configuration section of the Web Agent.
Note: Before you specify access lists to activate, you must first configure access lists.
For information about configuring access lists, refer to “Configuring Access
Lists” earlier in this chapter.
