Re: NAT to a broadcast addess using iptables?

I'm afraid it is not possible to do this with iptables. Is your goal to
do some kind of remote wake-on-LAN ?

Indeed it is - exactly that.

The problem with sending unicast packets to a sleeping host is ARP resolution. If your router supports the 'arp' or 'ip' commands, you could try to add a static ARP entry for your target IP address on the router :

$ arp -s <target_ip_addr> <target_mac_addr>

or

$ ip neigh add <target_ip_addr> lladdr <target_mac_addr> dev <lan_iface>
.
