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.

Apply

The RIPv1 Compatible option will transmit RIPv2 broadcast packets and receive both

RIP v1 and RIP v2 packets.

The direction configuration refers to the RIP request. Select In to allow RIP requests

from other devices. Select Out to instruct the Router to make RIP requests for routing
