Yes, but I have noticed some extreme weirdness.
one atempted http connection results in ipvsadm listing 6 active
connections to one realserver1 and 5 active connections to
realserver2. The second attempt at connecting adds 6 connects to RS2
and 5 to RS1.
the content is a very simple "you are connected to realserver1" page
no graphics or other external references, so to the webserver it
should only look like one hit.

:
:ah. the default route for the realservers for LVS-DR should _not_ be the DIP.
:It should anything else, like the client.
the default route is 128.52.37.10 which is an ExtremeNetworks
BlackDiamond switch (or at least it should be, wouldn't be the first
time I looked an obvious mistake in the eye for a week before someone
pointed it out...)
so my plan:
+----------+
| |
| Router | 128.52.37.10
| |
+------+---+
|
|
|
+----------+ |
| | | DIP eth0 128.52.37.173/24
| Director |---+ VIP eth0:21 128.52.37.21/32
| | |
+----------+ |
|
|
+---------+---------+
| |
| |
+----+-----+ +-----+----+
|Realserver| |Realserver|
| | | |
| | | |
+----------+ +----------+
RIP eth0:
128.52.37.4/24 128.52.37.253/24
VIP lo:21 (hidden)
128.52.37.21/32
Thanks,
