Did you get any errors from iptables? If not, then have you looked at
the output of

iptables -t nat -n -L

to get an idea of how iptables interprets your current rule sets in
the nat table? Iptables does what it does very well once you've got it
set up, but getting things set up properly and debugged is no walk in
the park.

Hmmm, you might. I'm not sure though if the definitive response here
is yes, or no. I'll need to consider it, or maybe someone will beat me
to it with a definite answer to that question.
