No it is not neccessary, though it is possible.
I'm not really sure that I understand where the confusion is.
Then your network should look like this.
[ Router ]

[ Linux Director ] [ Real Server ]
You probably want both the linux-director and the real-server to
use the router as their default gateway. Packets for the VIP will
go to the linux-director, then the real-server. It will process them
and send any replies to the end-user directly. If the end-user is
on a differen't network, it will be via the router.
If the end-user is on the same network, it will just send them straight
across the LAN. Actually, if the end-user is on the same network as the
linux-director and real-server, you don't need a router at all.
Just make sure, as I think you have, that the real-server doesn't
advertise the VIP over ARP, but is able to accept packets addressed
to the VIP that arrive.
