cluser, is the Virtial IP address, that is, the address
that end-users will connect to.
vscan1 and vscan2 are the addresses of the real-servers,
that is, the addresses that the linux-director forwards packets to.
The role of the linux-director, real-servers, and end-users
is covered in the HOWTO. Its also breifly covered here:
http://www.ultramonkey.org/3/lvs.html
The basic principles of LVS are quite simple. It only seems
complex because there are a number of machines and addresses involved.
But if you take the time to understand the basics, then everything
builds on top of that. In other words, there is no magic in there.
