Actually, I believe that NAT is _not_ turned on in the GENERIC kernel.
You'd have to compile your own.  (Of course, I could be wrong; you should
probably take a look at the GENERIC config file just to be sure.)

I don't think that you need to "install" anything if you are running
-current, but you will need a kernel with IP filter capability turned on.

Somewhere out there, there is a page about configuring NAT.  You might
want to check the current-users mail archives to find a reference to it.

Good luck!

Later.
