User Rules

[Patrick Nelson]

OK I am going to have to ask it.  I've been hoping that by reading all the
messages as well as the documentation that I would get it.  But for whatever
reason, it is not jumping out at me.

I don't understand user rules.  How and why they are used just seems to go
over my head...  So I must claim stupidity and ask the wealth of knowledge
on this list, is there is anyone who can explain it a little better to me?
I think I understand the mechanics and semantics of user rules.  Yes they
can optimize the flow through the rules, but for some reason I feel unable
to see why I would need them with my current firewall iptables script.  If
you know what I'm missing, that would metaphorically turn on the light,
could you please pass it on to me?
