Packet Filtering
Issue 4 May 2005 191
Note:
Note:
A packet is filtered against the ACL policies defined in the ACL list in the list
order. The packet is matched against policy number 1 first, then policy number 2,
then policy number 3, and so on until the packet finds a match or it exhausts the
list. If a match is found, the VSU applies the action specified in the policy to the
packet. If no match is found, the VSU applies the default policy to the packet. The
default policy is to permit the packet.
To edit, change the sequence, or delete a filtering policy:
1. Move to the Configuration Console window.
2. From the Contents column, select the VSU where you want to modify the ACL.
3. Click the Policies tab to bring it to the front.

for Packet Filtering.
5. From the ACL, select a specific filtering policy.
6. Use Table 11 for performing specific ACL management tasks.
7. When finished, click Save to save your work.
