The following instructions allow you to send a Wake-On-Lan (WOL) "Magic Packet" from the internet to a PC on your LAN behind the Actiontec NAT firewall.
From the PC you want to wake:
Unfortunately, the Actiontec firmware (as of version 184.108.40.206.220.127.116.11) ages out its ARP cache. This means that when it receives a WOL packet from the WAN, it may have "forgotten" the IP address associated with the MAC address in the WOL packet. The Actiontec also does not allow creating a port forwarding rule to the LAN broadcast address (192.168.1.255). To get around both of these restrictions, we need to create a static ARP entry in the router that associates an unused IP address (192.168.1.254) with the broadcast MAC address (FF:FF:FF:FF:FF:FF).
Telnet to router:
If you are unable to connect to the router, do the following:
At the prompt, enter either (depends on model of router):
Note: This static ARP entry will not survive a reboot of the router.
Now login to the Actiontec and Add WAKE-ON-LAN as a port forward protocol in the Actiontec:
Add the Port Forward Rule
SECURITY RISK: This port forward rule should only be enabled when necessary since it will turn any packet received on port 9 into a broadcast packet on your LAN. Recommendation: If the software you are using supports it, I would suggest using an obscure port number, such as 10009, rather than the well known port 9 (security by obscurity).
You can send a WOL packet from here: »/wakeup The DSLReports WOL tool only supports port 9.
If you have trouble, a WOL sniffer can be downloaded here: »www.depicus.com/download ··· uct=wolm
The above site also has a variety of other WOL tools.

Revised 12/31/08 to replace DHCP reservation with static ARP.
