broadcast

I have a host that receives broadcast queries on a UDP port. I would like to forward this broadcast traffic to another host from another network. Is it possible to port forwarding broadcast traffic using iptables? I have tried to specify package traffic as broadcast, but I didn't success. (-m pkttype --pkt-type broadcast).

If I recive unicast traffic on that port, the forwarding succeeds. I try to forwarding using nat table.(-A POSTROUTING -j DNAT --to-destinatiox x.x.x.x)

Thanks.
