Router/Firewall
Authored by: stilesja on Jun 18, '02 03:00:26PM

It looks like you are sending this on port 80 of a particular IP address. So, if I have port 80 of my router fowarded to my Mac and I send this request to the IP address of the Router should it then wake up the Mac?

I would however need to send the MAC address of the computer not the Router right?

Would this work? It would be very cool if it does since I am often gone all week for work and it would be nice to be able to turn the computer on and off remotely...

It only allows a sleeping computer to be woken up. If the system is shutdown then this won't work. The MAC address must be that of the computer you wish to wake.

The original post seems to indicate port 80 right after the broadcast address, however according to BroadbandReports.com WakeUp Page, a UDP packet is sent on port 9. Can anyone clarify which port(s) need to be forwarded for WOL to work thru a router? Thanks.

Just about any port you want.

The port you send to is entirely irrelevant. You could send it on another IP protocol such as ICMP that doesn't have ports at all, or on MS or Apple's old systems (NetBEUI/AppleTalk) or even plain raw Ethernet. All that's required is that the network card see a certain sequence of bytes on the wire.

It's common to use UDP port 9 because this is the "Discard" port from the early days of IP. Using this means WOL won't interfere with anything else you might have running. However, using some other port might be handy if it's already opened to allow another service to run. TCP port 80 would be a good example - anyone who runs a Web server would be able to use WOL on 80 without any further configuration.
