To be candid, I have not tinkered much with freebsd as a nat box. If you are using the same box to route and to shape, I'm sure the config will be different. My config (a bridge) is sitting between a cisco and my swicthes and my cisco runs nat so all the private ip's are shaped both in and out prior to the router nating it to a public ip.
