"ip addr ls" returns what I'd expect as far as IP's on the LB's. It's
just so -weird- that it would start taking traffic that belongs to a
couple Sun boxes and forward it to one of the linux boxes. I'll have to
see what I can do about getting the info from the router (that's not
something I have been graced with access to).
