Asus routers don't do WOL via WAN but Dlink can

[dikaiyang]

Long story short: Please help.

Dlink DIR-655, WOL works fine over LAN or WAN.

Asus RT-N65U, WOL works on LAN, but for WAN only the first few minutes.

To test I'm not insane, I put DIR-655 behind RT-N65U as a separate subnet and have RT-N65U forward my magic packet through UDP port 9 to DIR-655, then from there to the broadcast address in DIR-655's subnet, WOL works all the time even if the computer has been sleeping for more than minutes.

If I use RT-N65U to forward directly to my computer, from WAN it stops working after a few minutes.

Search suggests setting permanent ARP entry through telnet, which I did, but no change. Note all my devices use static IP already. I don't know why I still need to set static ARP, but I did it anyway.

Is this a shortcoming on Asus routers? So far I have to live with having things that need to be waken on my old DIR-655 in a different subnet behind RT-N65U. The drawback is the NetBIOS name doesn't get passed between the two subnets, only host names. So to access my NAS, I need to use an IP because it only has a NetBIOS name but no host name.

Any suggestions?

Has to do with the Green Ethernet layer 2 of the RT-N56U. Basically, the Asus firmware is not worth it, unless you want Cloud, support I would suggest installing Padavan's firmware. It is one of the best 3rd party projects I have seen in my time for modifying and updating the firmware for a router. It also has WOL support integrated, but you need to VPN first, go to the WOL page within the router, and then you can send a packet via a click of a button. Note that Ai Cloud has that feature too.

It is worth it, you gain better performance, and more functionality out of this 3rd party firmware than the stock firmware, IMO.

I don't understand how ASUS could not support such basic functionality as WOL.

It is not Asus' fault, technically speaking. It is the chip used for the layer 2 (switch), a bit of Realtek, their drivers, and Linux all in one.

Interesting. Well if true then it's just a general industry FUBAR situation. Of course it says ASUS on the package so they're accountable if it doesn't work. I was assuming it works on most other routers... do you think that's not the case?
