Try LVS-DR with transparent proxy method. you just have to have one line
added in to your real server packet filter, like :
ipchains -A input -j REDIRECT 80 -d VIP 80-p tcp
and more lines if you have more VIPs or ports.

I suppose you could cause your LVS box to be your default gateway. However
I don't think I'd recommend this..
