This is a bad bad advice in this day and age. If there are not enough 
users route caching will kill him. Here is a recent discussion of this:

P.S. I am not insisting that netfilter is superior in this regard, I am 
simply expressing common requirements and looking into ways of achieving 
them. If someone can point me to how to do this with kernel routes - I 
am all ears, since I recognize that the netfilter solution is not very 
elegant, although it works.
