I don't see any reason that you can't use the same NIC for multiple
puropses. If you are using LVS-NAT, then the real-servers probably
already have the Linux-Director as the default gateway. Just add
some IP tables rules to the Linux Director to NAT connections
that originate from the real-servers. If you are using LVS-DR,
then just make sure the real-servers have a route to the apache
web servers, probably a sensible default route will do the trick.
