if resin is not listening on $INBOUND_IF_IP:8900; or more realistically
0.0.0.0:8900, then it wouldn't work.  REDIRECT rewrites the dst IP to be
the IP of the receiving interface, since you don't even have an "-i $IF"
specified in that rule, resin would have to be listening on 0.0.0.0:8900
to even have a shot at working properly (or the machine in question
only has a single interface, perhaps?).
