I have no such trouble with natd; I am running 4.2-STABLE from 3-4
months ago. My firewall is a P90 with two $15 NICs, 32M RAM.

Please post a complete listing of your ipfw ruleset, as well as the
arguments you use with natd. I would suspect a bad rule somewhere in
your chain rather than a problem with natd.

Also, please explain in detail how your network is configured. Describe
the client machine, the gateway, the cable modem, client IP address,
gateway IP address, and anything else that even seems *remotely*
relevant.
