Firewall & DMZ
The Firewall & DMZ menu is used to define enforce specific predefined policies intended to protect against
certain common types of attacks.
A DoS "denial-of-service" attack is characterized by an explicit attempt by attackers to prevent legitimate
users of a service from using that service. Examples include: attempts to "flood" a network, thereby
preventing legitimate network traffic, attempts to disrupt connections between two machines, thereby
preventing access to a service, attempts to prevent a particular individual from accessing a service, or,
attempts to disrupt service to a specific system or person. To enable this function, tick the Enable DoS
Prevention checkbox.
