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.
Port scan protection is designed to block attempts to discover vulnerable ports or services that might be exploited in an
attack from the WAN.
The Service Filtering options allow you to block FTP, Telnet response, Pings, etc, from the external network. Check the
category you want to block to enable filtering of that type of packet.
When you have selected the desired Firewall policies, click the Apply button to enforce the policies. Remember to save
any configuration changes.
