i've got an "interesting" setup that, while it works just fine,
confuses in me in several "trivial" aspects.  it's something like
this:

		[internet]
		   |
		[router]
		   |
     +-------------+-------------+
[my host]		[another host]

the router receives several /24 blocks and a /20 from "the internet"
(where everything is effectively "unicast" since nothing outside the
router knows of the ultimate topology of our networks).  the router
sends me 1 address of the local /24 and a /27 from the /20, from right
at the top.

where is gets fun is how i use the /27.  i'm using it all up as /32
aliases, so i know that none of the addresses is a broadcast address
and my (perhaps limited cidr knowledge) tells me i ought to be able to
use all 32 of them (i am indeed using the effective "network number"
of the /27 i get).  then...just for fun...i'm routing *one* of the 

(1) why can't i use the -1 address?  i'm using the 0 address just
fine.

(2) why, when i traceroute to the forwarded address, do the icmp
"timed out" responses come from an address in the /27 instead of the
address i'm using that's part of the lan?
