Some platforms don't deal well relying on redirects.  The first time they
try to reach a destination, a redirect causes them to insert a host route
in their routing table.  If that destination moves (say a static IP
connecting to whatever access server they happen to hit), some OS's will
refuse to accept further redirects pointing the destination toward a
different gateway.
