As I said, iptables is not a strong point for me.  But when I read
your setup, it seems that you do not actually accept ethernet
broadcasts; you only accept 192.168.xxx.xxx packets, and obviously,
the NAS will not know to use that address range the first time.

Maybe something like:
-m addrtype --dst-type BROADCAST -j ACCEPT
