From Joshua Drake at LinuxWorld: "Nimda eats our bandwidth since other companies sharing our subnet are running infectious Windows 98, NT, and
2000 machines. These diseased, ill-maintained beasts from the land of insufficient light are now trying to infest our
stable, secure, long running, easy-to-use, well-behaved Linux machines. (Can you tell I'm a bit irritated?)
This has led me to start editing some of our firewall rules, and in the process, consider that, as we have recently
migrated to the 2.4 kernel, some people may be interested in how to create a Linux 2.4 kernel-based firewall quickly."
