9.9.1 Application Filter
With this option, you can define filters that can be associated with access rules
for filtering commands of SMTP, FTP and RPC services and HTTP file
extensions.
* For FTP, SMTP and RPC service filters: If an application filter is con-
figured to allow certain commands, SL6000/SL6300 will allow ONLY
those commands. If an application filter is configured to deny certain
commands, SL6000/SL6300 will deny ONLY those commands.
* For HTTP application filter: The application filter can be set only to
deny file extensions.
1. To add a new application filter, choose the Filter type first from the
drop down list.
2. Then choose the Add New option in the drop down list, enter the
Filter name in the text box.
3. Choose the Protocol from the drop down list.
4. Enter the Port value
5. Choose the action as Allow or Deny depending on whether you’d
like to allow or deny the commands. You can also chose to log mes-
sages whenever SL6000/SL6300 drops or allows a packet based on
the filter you’ve selected.
6. You’d also have to type the commands in the Command text boxes
depending the type of the filter you’re adding or modifying.
