The VIP is the IP that the client knows about, in your case
202.88.178.203
The DIP is an IP on the realserver network. You
assign this from the network block you have.
In the case of tunnelling to the realservers,
the DIP will be an IP on the network that you
use to connect to your realservers. If that
IP is in the 202.162.228.0/24 network, then
you don't need to use LVS_Tun, you can use
LVS-DR. If the IP is not in that network,
then you must use LVS-Tun.
