Mmm,
Sounds to me that you have the arp problem.
Did you have a look at:
http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.arp_problem.html
I use the hidden patch to solve this, is the best solution I think.

Subject: LVS-DR problem, getting me not enough sleep ;)
Hi,
I'm new to LVS, but after 2 days of studying and testing i know my way
around. I have succesfully build a LVS-NAT setup, however the actual
system needs to be LVS-DR. And with the DR I have some problems. To
simplify it I test with one realserver. My problem: when i connect on
132.229.42.163(https) i get a "page not displayed" in my browser. When i
watch the state of lvs with ipvsadm i see a number of inactive
connections. I have tried a lot (late nights :D) but i can't see my
mistake in this setup. My setup is:
loadbalancer:~ # uname -a
Linux loadbalancer 2.4.21-138-smp #1 SMP Fri Oct 31 00:51:31 UTC 2003
i686 unknown (SLES 8)
loadbalancer:~ # ipvsadm -L -n | head -1
IP Virtual Server version 1.0.10 (size=4096)
loadbalancer:~ # ipvsadm -h | head -1
ipvsadm v1.21 2002/07/09 (compiled with getopt_long and IPVS v1.0.6)
o Using LVS-DR, gatewaying method.
o Load balancing port 443 (https) non- persistent (production
will be persistent)
o Network Setup:
