I think it is the wrong answer to any possible problem (compared to
changing DNS or whatever it takes to make the connection request go to
the right place on its own). Your iptables DNAT line would work to get
the packet to the other host - and you should be able to see that with
tcpdump. However, when host B responds back to the original source
address it won't complete a connection to the socket waiting for
something from host A.
