3 In the Name field, enter no IM for the application control list name.
4 Select OK to create the new list.
5 Select Create New to add a new list entry.
6 For Category, select im.
7 For Action, select Block.
8 Select OK to save the new list entry.
9 Select OK to save the list.
Next you will enable application control and select the list.
To enable application control and select the application control list
1 Go to Firewall > Protection Profile.
2 Select the Edit icon of the protection profile specified in the outgoing policy.
3 Expand the Application Control section.
4 Select the Application Black/White List check box.

No IM use will be allowed by any firewall policies using the protection profile with the no IM
application control list.
