How to make udp packet jump from input to forward chain?

Hello.

Here is the problem:

Host1 at 192.168.0.150 broadcasts UDP traffic to 255.255.255.255 src-port is 8596. Network is 192.168.0.0, network broadcast address is 192.168.0.255. Using Torch, I can see this traffic on router (one interface on MT router is connected on the same broadcast domain like Host1, call it LAN if you want), I can also see this traffic destined to 255.255.255.255 in Input chain and do with it what ever I want, but only in Input chain.

Question is how to forward somehow this traffic to Forward chain, so I can use dst-nat? Instead of 255.255.255.255 as destination I would like to get this UDP traffic destined to address 192.168.8.150 (5 hops to 192.168.8.0/24 from MT router I am speaking of). Is it possible to dst-nat in this case?

Thanks for efforts
