Hmm... I don't remember that manual.  Clearly post-dates the modular 
kernel, whatever it is, but also talks about using iptables...  As Mark 
Heilpern's already replied, I don't think the NAT stuff is being built 
in the current (or any previously released) kernels, so that's unlikely 
to work unless you customize the kernel build.  And I don't think the 
iptables binaries are built as part of any released root_fs either, so 
the fact that command's running at all is pretty unusual.  And then as 
Mark points out, it's not entirely clear why you need to turn on NAT 
anyway on the gumstix, unless you're doing something like using it as a 
router from bluetooth land to usbnet or something.

Generally the online stuff is the most up-to-date and contains the best 
way of doing things.
