If it's useful, here's a write-up on wake on LAN and related topics from a while back, with links to various other documents, tools and mechanisms.
Various of Apple's wireless devices provide what's known as a sleep proxy for the target system. That is, the wireless devices mimic "being" the target device, and will wake the target device when there's activity determined to be necessary.
For the wake-on-LAN stuff, all of the intermediate routers have to support the traffic, and they almost certainly won't... As an alternative, get a firewall with a VPN server, VPN to that, and have at.
If you're particularly inclined, there are various fairly affordable network-connected power strips, or (more expensive) network-connected battery-backed power supplies; remote-managed less-interruptable power supplies. These can be used for controlling power, once you're connected to the VPN server on your LAN.

I pushed "solved my problem" accidentally and the iPad won't let me change it. But maybe it will solver it for me - you certainly have pointed the way to finding a solution. If I get it working, I will follow up here. Thanks, Mr. Hoffman.

Question? Are you looking for WakeOnLan from inside your home? Or are you looking for WakeOnLan from outside your home?
I can understand the difficulty if WakeOnLan outside the home is giving your problems, and is one of the great benefits to the Airport Extreme (and Time Capsule) Sleep Proxy service.
However, if you are having problems inside your home, then that seems rather strange.

Bob, I'm trying to do it just in my house. It used to work from the Macbook (Lion) to my G5 (10.5.8), but haven't tried it lately. I need to gather more data and get bock to you.

Are you using the WakeOnLan utility, or some other means to wake the sleeping G5?
Also is the G5 connected via Ethernet or WiFi ? I ask, because I'm not sure the G5 class systems had Wake-on-LAN capabilies I've WiFi. Only Ethernet.
Currently Being ModeratedMay 1, 2013 12:05 PM (in response to BobHarris)Bob, you are right. The G5 (ppc w/ 10.5.8) is only on ethernet and I woke it from an iBook with an open source app ( I think it was called "Wakeup" ) which was also on the same local ethernet. So now the wifi router (Verizon Actiontec) is "in between" and that may be where the needed setting is.Boyd

It has the ability to tell you every device is sees on your home network (a nice side benefit).
Do you have more than one router in your home. Note, if you got a second WIFi router to give better coverage, you might have it configured as a blocking router that could affect wake-on-lan signals.

No, it is just a single router. But I don't know if it is passing the WOL signal or not. I hope to try WakeOnLan app tomorrow and will let you know what I find. Thanks.

Bob, I went ahead and installed it just now, and it works! I was mistaken on thinking that any request to connect to the Mountain Lion machine would wake it up. Anyway, the WakeOnLan does a great job in showing who/what is awake, and in waking up the sleeping ones.
Thanks a lot everyone who responded.

By the way, I didn't have to change anything except install the WakeOnLan app from readpixel.com. Of course, my Mini already had "wake on network..." selected.
