• To selectively block/allow inbound or outbound traffic between inside host/networks and 
outside host/networks. Remember that filters can not distinguish traffic originating from

• Use the firewall if you need routine e-mail reports about your system or need to be alerted 
when attacks occur.
• The firewall can block specific URL traffic that might occur in the future. The URL can be 
saved in an Access Control List (ACL) database.
