how to forward multicast to multicast via iptables

I want to forward incoming multicast traffic to other multicast address listened on my server interface. My machine running on Ubuntu 14.04. Have a incoming traffic on 239.0.0.1 udp port 1001, want to forward to 224.0.0.1. I wrote the following rule. iptables -t nat -I PREROUTING 1 -m pkttype --pkt-type multicast -d 239.0.0.1/32 -p udp --dport 1001 -j DNAT --to-destination 224.0.0.1:1001 But there is no any traffic matching it, root@serv:/root# iptables -t nat -L -nv --line Chain PREROUTING (policy ACCEPT 3 packets, 180 bytes) num pkts bytes target prot opt in out source destination 1 0 0 DNAT udp -- * * 0.0.0.0/0 239.0.0.1 PKTTYPE = multicast udp dpt:1001 to:224.0.0.1:1001 also when I listening my p3p1 inteface with tcpdump there is show that there is incoming traffic to 239.0.0.1.
