If you are using LVS-NAT and your end-users are on the same network
as the Linux Director and the Real Servers then the Linux Director
is probably sending ICMP redirects. You should be able to disable
this behaviour using /proc.
The next problem is that you have to make sure that when
the Real Server replies it sends the reply packets to the Linux
Director and not directly to the End-Users. The latter will not
work as the packets will not have been un-natted. Usually
this will invlove some routing fun and games on the Real Servers.
There is an entry in the HOWTO on this:
http://www.linuxvirtualserver.org/Joseph.Mack/HOWTO/LVS-HOWTO.LVS-NAT.html#one_network
However, my recommendation is that if you want to have Real Servers
and End Users on the same network, use LVS-DR. It is fundamentally
better suited to this kind of work.
