I don't have a natd.conf file on one of my development boxes, but I do have 
this in /etc/rc.conf:

firewall_enable="YES"
firewall_type="OPEN"
natd_enable="YES"
natd_flags="-redirect_port tcp 10.0.1.9:5800-6600 5800-6600"

Yeah, it's wide open and insecure, but it does work and might be a starting 
point for you.
