Problem
being...with typical routing setup, you've got one of
two
scenarios...either the eth0 of the routing box is the static
that's
assigned "to route to" (using your terminology to help clarify
here).
Meaning that the static is pulled out of the /30 block, meaning
there's
only one other address available...one short...
Or, you have
the static IP "to route to" :), and then the /30 block has
to have one of
the IP's assigned to the eth0 of the same box doing the
routing which means
you've got two IP's assigned to the same box...still
one short.
:/
You could do a couple of /30's and have multiple IP's assigned to
the
eth0 card of the router....but then you're still chewing up the
same
amount of space as a single /29 does with fewer useable
addresses...it
does have the upside of letting you assign non-contiguous
addresses if
your IP space is that fragmented.
