Yes. You can use any range but advantage of K12LTSP is that hardly any
configuration is needed if you go with defaults.
So what is IP that has been assigned for your server? This needs to be
set up in number of places. Before you go in to that confirm that in all
other respects your system is following the k12LTSP scheme with two NIC
cards. One for internal Thin client network and the other to be
connected to your building Network. Ideally this IP should be assigned
to gateway - the second NIC card eth1 and go with default IP scheme for
all thin clients on the downside of your servers first NIC - eth0.

That's what I have given. you just have to know the proper IP address of
both the machines.

You sure can provided it is one on one cable (cross over cable)
Generally you do not get these cables.
