I do this on my home network, to forward incoming http requests
to my
web server. I changed the natd.conf to this -

use_sockets yes
port 8668
alias xxx.xxx.xxx.xx           (enter your ipaddr provided by
your isp)
interface xxx                  (enter your nic with the above ip
addr)
redirect_port tcp xxx.xxx.xxx.xx:http 0:0 http   (enter ipaddr of
the server the 
                                                  requests are
sent to)

You will want to make this for whatever port you want to forward,
in my case
it's port80, http.
And of course you'll need the necessary lines in rc.conf
regarding natd. But
if you already have natd running that should be done.
