Any packet that can be matched by a ipfw rule can be redirected transparently to another port or machine. Redirection to another port mostly makes sense with tcp, where a session can be set up between a proxy and an unsuspecting client. Redirection to another machine requires that the other machine also be expecting to receive the forwarded packets, as their headers will not have been modified. /sbin/ipfw must be recompiled!!!
