IP Rules
Use the IP Rules screen to define rules for IP-based standard ACLs. The access list 
definition includes rules that specify whether traffic matching the criteria is forwarded 
normally or discarded.
Note: There is an implicit deny all rule at the end of an ACL list. This means 
that if an ACL is applied to a packet and if none of the explicit rules 
match, then the final implicit “deny all” rule applies and the packet is 
dropped.
 To add IP rules:
1.  Select Security > AC
L > Advanced > IP Rules. 
In the following figure, an IP ACL exists, and one rule has been configured.

2.  From the ACL ID list, select the IP ACL for which to create a rule. 
3.  Click the Add but
ton. 
The screen refreshes, and additional fields appear.
