Yes, the fwmark only selects routes but only the local route
delivers the traffic. If you play in 2.4 you can see that some network
tricks depend on the fact whether your routes are symmetric. In the case
with the replacing the local addresses with local routes (assuming not
in table "local") you can notice that you can't talk with such addresses
to the world. This involves the ICMP replies that LVS sometimes sends.
In 2.4 they are not sent in such cases. You need valid local routes in
table "local". Of course, there are patches to fix this behavior but I
didn't tried them.
