        Yes, this is the default setup

        Hm, so it looks like redirects are not sent here, I assume this
is Linux 2.2 because in 2.4 I'm sure redirects will not be sent. LVS
in 2.4 lookups the NAT-ed real server using the output route function
while LVS for 2.2 lookups the real server using the input route function
and a redirect is usually returned when the forwarding device matches
the input device, which is our case. But may be I'm missing something in
theory. I'll check it this weekend too.
