•The firewall provides e-mail service to notify you of routine reports and when alerts occur.

13.7.2.1When To Use The Firewall

•To prevent DoS attacks and prevent hackers cracking your network.

•A range of source and destination IP addresses as well as port numbers can be specified within one firewall rule making the firewall a better choice when complex rules are required.

•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 an inside host or an outside host by IP address.

•The firewall performs better than filtering if you need to check many rules.

•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.
