I'm afraid not, all our systems are setup using masquerading NAT. That
was going to be my next question if it turned out (as it did) that
you're using kosher RPMs. :)
I've only ever had LVSes configured with NAT so have no experience and
only a vague memory of how DR works from the docs. If no one here can
point you in the right direction there's a dedicated LVS list too
which might be worth searching the archives of and then questioning if
you can't find an answer.

And, to follow up my own post, I've just had a quick look through my
LVS list mails and spotted:

There's no follow up from the OP which may or may not be a good thing. :)
It appears a kernel upgrade to 2.6.18 (!) may help. You might want to
fire off a mail to the OP and ask if he had any success. I have the
un-obfuscated address in my mailstore, I'll send it offlist.
Will.

Thanks for your help, but I will wait for an official patch from centos,
I hope that I will be heard.
