A NIC can have many addresses (up to 256 I believe) on it from different and
unrelated networks. The main reason to use multiple NICs are that packets are
separated into different physical networks. This makes writting filter rules
easier and allows more throughput than one card can handle.
The VIP is contacted by the client. If the client is on the internet, then
the VIP must be a public IP. The RIPs are usually private IPs for both LVS-DR
and LVS-NAT. One NIC on the director can have both the public VIP and the
private DIP.
