Wake-on-LAN (over internet) working?

[mavis]

Just wondering if WOL is working for anyone.

I'm using WakeUp on my iPhone; it works on the LAN but not over LTE. I've got my AirPort Extreme set to broadcast UDP port 9 over the entire network (sending to 10.0.0.255; my iMac is 10.0.0.2) but it simply does not work.

Has anyone had success using WOL over internet with Mavericks?

Anyone? I can't be the only person who wants to use WOL from time to time ...
