        For now, these are the only known problems. If your problem
is different we will mention it here.

        What shows traceroute from real server? Is it working before
adding IPVS commands? Please, make the checks mentioned in this HOWTO.

You can read about it here:

        Sorry. I can't understand what happens. If you have something
to show it, please do it. The debug from LVS will be useful. If not,
I don't have more answers to you. "It works here". What IPVS version
are you using now?
