I did but I don't get the same results. The only time the vip even turns up in
the arp cache of the client is when the director is connected and then it's
the directors mac address. Without the director the client have no idea of
the vip only the realservers. And when I ping the vip on the realserver that
has the vip on the loopback there is no sign of any mac address in the arp
cache on the realserver.
So it seems ok to me.

That doesn't seem to be true for HPUX.

So HPUX seems to handle the 127.0.0.0/8 in some different way.

I don't see any reason to trick the server after my test, do you?

Sure will let you know. Many thanks for your time.
