Notice the Forwarding is "Route", it should say "local node" I think.
What ipvsadm command did you use?

Local node only works reliably (I've found) when
you specify the virtual address and SAME PORT.
I.E. add as a real service in your case.


p.s. I've never tested this with direct routing so I may be wrong.
