    Seems like you know a bit of what you're doing, so have a look at Rusty's
    Remarkably Unreliable Guides at
    http://www.netfilter.org/unreliable-guides/

    There are even figures of which table/chain is called where in the routing
    process ;-)

    Also, the man page of iptables is quite exhaustive once you know what you
    want.

    Ciao,
