You need a route via the loopback to make this work.  This should be
added automatically if you use /etc/ifaliases.  I believe 'ifconfig' adds
this automatically when you add the "primary" address.
(e.g. my machine has a route via loopback for it's primary ethernet's
ip address)

'route add $alias 127.0.0.1'
