Hi Beerfloat,
I have an AEBS at home connected to the iMac at home, and a Time Capsule at work. Does it support this? And I'm having a little bit of trouble following what you're suggesting I do, can you elaborate a bit on what I'm trying to achieve wit this PAT mapping and UDP?
thanks,
Mark
Can't say for sure that it works on an AEBS. Same for the wireless. Some do, but chances are a lot better with wired networks.
Normally you would send a WoL packet on a LAN as a broadcast UDP on port 9. So basically you'd be sending the packet to 255.255.255.255:9 and all devices on your subnet will receive it, including your sleeping Mac. You can also specify a more limited broadcast address like, say, 192.168.1.255. You could even send it to a unicast address, but when the computer has been asleep for a while its IP address tends to disappear from ARP caches and that'll stop working. So basically, we wanna send it to a broadcast address.
Almost all routers will allow you to set up a list of static forwarded ports from the outside interface to the inside interface. But not all will allow you to set a broadcast address as internal target.
Say your external IP address is 10.1.1.1 and your MAC is on an internal LAN with IP address 192.168.1.20. What you'll need to do is set up a port forward 10.1.1.1:9 to 192.168.1.255:9.
Then use wakeonlan or a utility like that from the outside like so:
wakeonlan -i 10.1.1.1 00:de:ad:be:ef:40 (ie MAC address of your card)
If your router supports it, I would map some higher port number on the outside to 9 on the inside. Don't necessarily want outside port scanners to know what you're doing.
So say have a mapping 10.1.1.1:23456 to 192.168.1.255:9
wakeonlan -i 10.1.1.1 -p 23456 00:de:ad:be:ef:40
