Wake on lan via site to site VPN which firewall in the middle

I'm trying to do Wake on Lan over l2l VPN Tunnel. The topology is as follow

pc1 -> L3 Switch-> asa firewall --l2l vpn ---  asa firewall -- L3 Switch

asa is running 8.2 and the remote one is running 8.4  with routed mode

I have all the essential configuration for WoL already on L3 switch.

On the SVI, I have ip helper address and ip directed-broadcast ( for now i have an access-list that allows any to any during this testing period.)

(config)# ip forward-protocol udp

I'm pretty sure this has to do with something on the firewall not allowing broadcast address to forward via the l2l vpn tunnel. I also about ASA does not forward broadcast with routed mode and that I should have a proxy server to forward udp packet on the remote site to confirm that.

Do you guys know if WoL is available in this set up? if so, What need to be done?

Thanks

Try re-thinking the design -- do you have, or can you set up, a simple IIS web server inside the network that you can access from outside?

A very small VBScript call can do exactly what you need.  I already do it with code like this:
    MACAddress = _mac_address_to_wake_up_
    Set objShell=CreateObject("wscript.shell")
    strCommand="E:\WakeOnLan\mc-wol " & MACAddress & " /a 192.168.1.255"
    Set objExec=objShell.Exec(strCommand)
    Set objExec=Nothing
    Set objShell=Nothing

Open in new window


I then have a small front-end web page that allows me to pick a computer name and MAC address to wake up, which inserts that data into a database when I hit Submit.  Then, this process takes the MAC address out of the database and broadcasts the magic packet.
