Yes you should be able to use any of the methods you want.  I recommended
LVS-DR initially in my setup because I was confusing it with PPTP, which
doesn't like being behind a masq box.  Sorry about that.

I think you are right to want to use LVS-NAT, it should allow much better
security!  You will simplify setup and improve security all in one big
swoop.  Hmm I think you'll have to congratulate yourself with a beer or two
tonight :)
