I *thought* the most recent ISCdhcpd handled it, too, but I could be mistaken (I read the DHCP RFC's more than I read the code). > I am trying to forward UDP packets from microwave bridge.

So I also want to use natd.) You may be looking for the wrong tool. Probably you want to use an "DIVERT" rule in the ipfw, then in the user space program at the other end of the divert, use the BPF to forward the UDP packet. Port 170 UDP is reserved for Network PostScript print servers, btw... so you are doing nasty stuff. 8-(.
