    Your public IP might be a Class B address…

    But internally, you have Class A addressing via NAT.

    Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

      @Wayne-Workman “The three default subnet masks are 255.0.0.0 for Class A, 255.255.0.0 for class B, and 255.255.255.0 for Class C.”

      From this my impression is we have a class B subnet mask but I could be wrong, but I dont think this matters as whichever class it is, wake on lan isnt working lol

        OK… troubleshooting time I suppose.

        You need to find a utility that will send a wake-on-lan packet to your desired IP address… (the broadcast address).

        Then,
        Go on site and see if you can broadcast a WOL packet and see if computers start up. If it works, then your switches / router configurations are to blame.

        If it doesn’t work… maybe make sure WOL is enabled on those computers… maybe try to WOL an individual client and see if that works.

        Report back and we will go from there.

        I’d recommend trying this one:
        http://sourceforge.net/projects/aquilawol/

          @Wayne-Workman I just downloaded this program and tested it exactly how you had asked and the computer wakes up perfectly fine. I then turned it off and attempted to wake on lan again from FOG and again to no avail. So you’re saying it’s a switch/router config thats to blame but I am not sure where that could be.

            One thing you can try is sending the packet from the command line with wakeonlan

            wakeonlan 28:D2:44:0C:D9:9B
            Sending magic packet to 255.255.255.255:9 with 28:D2:44:0C:D9:9B
            

            Do you have wireshark? If so set the filter to wol and see if you get a packet, if not your switches may be blocking it.

            Here were the relevent Cisco commands I had to set on our 4500:

            ***fogserver vlan***
            interface Vlan2					
             ip helper-address 10.2.255.255
            !
            ***high network vlan***
            interface Vlan1					
             ip helper-address 10.1.0.119
             ip directed-broadcast 101
            !
            ip forward-protocol udp echo
            ip forward-protocol udp discard
            
            access-list 101 permit udp host 10.1.0.119 any eq echo
            access-list 101 permit udp host 10.1.0.119 any eq discard

              I attempted to do that and by the image you see I tried exactly the same thing and the computer doesnt turn on.
              I have wireshark but have never used the program to know how to filter to wol

                @szecca1

                In wireshark first select your connection and then click start
                upload-e49875ba-fccb-4db4-bd77-9fbaf92d62fe

                Once started type wol into the filter box and click on apply.

                This is what it looks like when I send a wol:
                upload-9b5bc60e-7570-4aff-83dc-0481f839b087

                  Ok i did exactly what you said. the top one is from a computer in the 10.1.x.x address and the bottom one which is the one that worked is from the 10.2.x.x address.

                    The top one is on the same subnet as your fog server correct?

                    Try running wireshark on the bottom machine (i assume it is on the same subnet as your target), but send the wol from your fog server.

                      @cml You are correct, the top one is on the same vlan as the fog server.

                      I just ran wireshark on the bottom machine and ran wol from the fog server and wireshark didnt pick anything up

                        Your switch is not forwarding the packets across subnets. Do you know what manufacture/model your L3 device is?

                              Not familiar with Nortel’s configuration, but there is this post:

                                @cml I double checked and we already enabled that portion of the switch and still nothing. But I did find a configuration on the switch from broadcast addresses and nothing is listed. Do you think if I entered the broadcast address there,the passport would then allow the packets to pass through the VLANs?

                                    @Wayne-Workman I put an email to my company because I didn’t want to try it and cause my entire network to go down. As soon as I hear from them I will give it a try

                                        @Wayne-Workman With this situation and me not being the network admin, my company would probably prefer me going directly to them first and then if possible calling Nortel. I will definitely keep you guys updated.

                                          I think you are saying that FOG requires that broadcasts be allowed to travel across the router to other VLANs.
                                          This makes no sense - and even if it could be done - would not be advisable.
                                          That’s what I’m being told, does this sound correct?
