Those lines (400 and 500) sure look like they could cause trouble. Try
chopping them up per port number/range across multiple lines.

ipfw and natd are nice for the quick-and-dirty setups, but if you need
something more predictable, configurable, and debuggable....switch to
ipfilter and ipnat. You'll find yourself very much in control over your
firewall/nat environment.
