From the howto, IPCHAINS-HOWTO.gz:
| 5.7. How Do I Set Up IP Spoof Protection? | | IP spoofing is a technique where a host sends out packets which claim | to be from another host. Since packet filtering makes decisions based | on this source address, IP spoofing is uses to fool packet filters. | It is also used to hide the identity of attackers using SYN attacks, | Teardrop, Ping of Death and the like (don't worry if you don't know | what they are). -- Cheers, Carlos Robinson
