I'm assuming you're using arptbles_jf?
Is that setup correctly?
Can you provide the arptables -L output from the real server and the snippet
from lvs.cf that applies?

Subject: Re: [lvs-users] CentOS 5 apache real servers don't respond
For now I am just trying to get a simple html page to load. I am
listening on all IP's and I did restart apache after adding the Virtual
IP to my apache real server just to make sure it was listening on that
IP now as well.
I am using a virtual server setup (many sites on one IP) in apache, if
it matters.
Anyone have any thoughts about my direct routing concerns and the setup
for that?
