But it still leaves unanswered one question that I really would appreciate your (or somebody's -- Lynn?) help with:

iptables lets me specify state rules for ACCEPTing all packet types, not just TCP. For UDP, what test does ipchains apply to a packet to classify it as NEW, ESTABLISHED, RELATED, or INVALID? I see nothing in the UDP spec that it can use (for NEW vs ESTABLISHED, specifically). Is this a bogus capability, or is there some neat trick that I cannot fathom?
