,  ipfw,   man ipfw:

             fwd ipaddr[,port]
                     Change the next-hop on matching packets to ipaddr, which
                     can be an IP address in dotted quad or a host name.  If
                     ipaddr is not a directly-reachable address, the route as
                     found in the local routing table for that IP is used in-
                     stead.  If ipaddr is a local address, then on a packet
                     entering the system from a remote host it will be divert-
                     ed to port on the local machine, keeping the local ad-
                     dress of the socket set to the original IP address the
                     packet was destined for.  This is intended for use with
                     transparent proxy servers.  If the IP is not a local ad-
                     dress then the port number (if specified) is ignored and
                     the rule only applies to packets leaving the system.
                     This will also map addresses to local ports when packets
                     are generated locally.  The search terminates if this
                     rule matches.  If the port number is not given then the
                     port number in the packet is used, so that a packet for
                     an external machine port Y would be forwarded to local
                     port Y.  The kernel must have been compiled with the
                     IPFIREWALL_FORWARD option.
