port forward (dst NAT) for udp packet with 255.255.255.255 as destination IP

Hi Guys,
I have a network like this.

pc 1, pc 2 is behind nat. I want to send an udp packet from source Ip 30.42.0.2 (pc 3) to destination IP 255.255.255.255 and destination port 1092. I want to use dst nat to forward packet from destination 255.255.255.255 and port 1092 to the internal network (pc 1 needs this packet to be configured).
Thanks so much.

This problem is a little different from routing for the 255.255.255.255 destination packet; it is port forward for packet UDP with destination 255.255.255.255.
Thanks so much.
