ip_forward is needed, icmp_redirect usually does not need to be
modified.

This should not be neccessary.

You can do that if you would rather, however be careful to
make sure that the real server does not make arp adverisments for
the VIP. If you use lo, then this can easily be done using arp_ignore
and arp_announce. If you want to use eth0, then arptables is
probably the way to go.
