That is the simplest way to get it done. One thing that might help is
knowing the location of your thin clients. Are they going to be
scattered throughout the building or in one room? If it's one room Nils
hit it right on, just do a default setup with two nics and you're set.
If they are scattered then you will have to do more work.
