Another device that can be configured with an all F's MAC clone is the D-Link WBR-1310 Version B1.
The D-Link WBR-1310 is pretty straight forward:
1. Restore factory default configuration
2. Set the Internet (WAN) connection type to static IP
a. IP Address: 192.168.1.254
b. Subnet Mask: 255.255.255.0
c. ISP Gateway: 192.168.1.x (were x can be your real gateway or something bogus like 252)
d. MAC Address: FF-FF-FF-FF-FF-FF
e. Primary DNS Address: 192.168.1.x (were x can be your real gateway or something bogus like 252)
3. Disable Wireless Network
4. Enable Remote Management on Port 80
5. Disconnect from the LAN port, and connect the WAN port to your network.
6. Configure ISP Router to forward port 9 to 192.168.1.254
7. Configure target computer(s) for Wake-on-LAN
Test:1. Send WoL packet from internet tool such as the Broadband Reports WoL tool on port 9
2. ISP Router sends out an ARP request for 192.168.1.254
3. The modified device (192.168.1.254) responds to the ARP request with it's all F's MAC.
4. Router forwards the WoL Packet to 192.168.1.254 via Ethernet address FF:FF:FF:FF:FF:FF, a broadcast.
5. Machine specified in WoL packet wakes up.
Success!!! No more having to make the manual static ARP entry which does not survive a router restart.
