on the realserver the service is listening on the VIP (as it 
must, because that's where the client sent the packet). The 
realserver replies from the VIP. The packet goes back to the 
client. The RIP is needed so that the director can find its 
MAC address and send a layer 2 packet from MAC_DIP->MAC_RIP.
