Port Forward to broadcast ( in 1.5 request

    I used to have a BEFW11S4v4 which allowed port forwarding to the broadcast address. This was useful because I setup a UDP port forward that allowed me to send a Wake On Lan packet from outside my LAN to turn my computers on.

    Now I have a WRT54GS, but x.x.x.255 port forwards aren't allowed and there is no other way to send a WOL packet from the Internet that will go through the router.

    Is it possible to allow this in the next version? I know it's a security risk, but you could have a prompt that lets you know about it or maybe even limit it to UDP port forwards, or even allow some other way to send WOL packets through.

    I am having the same issue

    I'm also unable to specify x.x.x.255 in the port forward to allow a Wake On Lan signal in from the internet to broadcast the UDP packet to my internal network.

    Would it be possible to get this included in an upcoming release of HyperWRT?

    Here are the details on setting up this type of port forward: http://www.broadbandreports.com/faq/6790

    Unfortunately the port forwarding is only allowing the IP Addresses 4th octet 0-254 to be saved to the configuration.

    Able to get WOL working using SVEA


    I was able to get WOL working using SVEASOFT firmware.

    I had to use the SSH Server built into the firmware. I loaded OpenSSH on my Laptop. Configured SSH using http://rage.against.org/SetupSSHPublicKeysOnWRT54G as a guide

    Created a "config" file in my .ssh directory in my windows profile with the following:
    host computername
    hostname www.xxx.yyy.zzz <-- Public IP
    port 22 <-- SSH Port

    The Command I use to connect is:
    SSH root@computername -i ~/.ssh/id_rsa -o "Protocol 2"

    The command to wake the computer is:
    /usr/sbin/wol --ipaddr= xx:xx:xx:xx:xx:xx

    Where is the subnet broadcast, and the xx:xx:xx:xx:xx:xx is the MAC address of the NIC. This can be obtained using IPCoNFig /ALL from the command prompt

    I have a batch file with the wake command echoed to the screen so I can copy and paste it into the SSH session.

    This is more round about than I thought it would be, but it does work like a champ for me.
