  I've had problems with using aliases when the alisesed address is 
outside the current subnet.  It appears to have difficulty doing arp 
correctly.  This is rather annoying, because I'd like to use this feature 
to re-locate a nameserver to a different subnet, and then setup host 
routes on a couple intermediate routers.

  BTW, I had the exact same results with FreeBSD 1.1 too, so it may be a 
old BSD thing.
