9.2.2 DoS

Configuration

The RX3141 has an Attack Defense Engine that protects internal networks from Denial of Service (DoS)
attacks such as IP spoofing, LAND, Ping of Death, smurf and all re-assembly attacks. It can drop ICMP
redirects and IP loose/strict source routing packets. For example, a security device with the RX3141 Firewall
provides protection from “WinNuke”, a widely used program to remotely crash unprotected Windows systems.
For a complete list of DoS protection provided by the RX3141, please see Tables 2.1 and 9.2.
