    @Tom-Elliott Ok so I installed and activated the plugin and when I click on it i am getting this:
    Capture.PNG

    You’re saying all I have to do now is name the broadcast whatever i want and then give the broadcast IP of what VLAN it is?

          That’s a pretty awesome plugin… for real…

          I’m going to use that when I setup FOG in vmware at our central site.

            @Tom-Elliott I apologize in advance but where would I get this broadcast ip? Would this be the gateway ip from each building? I’m not sure where to pull this broadcast IP from?

              @szecca1

              You basically jot down any valid IP for a network, then jot down your subnet mask.

              Convert both to binary, with each of the four octets separated by a decimal as normal.

              Then, for each ‘0’ in the subnet mask, you’d flip that to a 1, but you’d still use the network portion of the valid IP, those binary bits would just “fall through”

              So… example time…

              Subnet mask: 255.255.240.0

              IP 10.2.3.8

              Binary IP Subnet:

              00001010.00000010.00000011.00001000
              11111111.11111111.11110000.00000000

              (Client IP network portion: 00001010.00000010.0000 Client portion: 0011.00001000)

              the fall through numbers for the network address:
              00001010.00000010.0000000.00000000 (Where 1 is set in the subnet mask, binary from the client ‘fall through’ to form a network address)
              This gives us a network address of 10.2.0.0

              The broadcast address is the network address combined with all-on client bits.
              00001010.00000010.00001111.11111111
              (binary in the subnet mask set to ‘0’ ‘fall through’ to the broadcast address as ‘1’)

              Convert to decimal: 10.2.15.255

              So, 10.2.15.255 would be the broadcast address for that IP and that subnet mask.

              And, that’s correct, that’s my particular building’s broadcast address.

                @Wayne-Workman The 10.2.3.8 address that you used in your example, where did you get that from? Is that just a random IP of a client in the 10.2 VLAN or is that something in particular?

                  @szecca1 It’s a random (but valid) IP for my network.

                  Also, don’t think of it as a V-LAN… that’s not correct. Think of a “network” as a broadcast domain, or a subnet.

                  V-LANs came along WAY after the specs for TCP/IP and routing were developed. V-LANS are just a way to logically separate traffic within the same device.

                  V-Lans have just numbers assigned… I.E. 5, 6, 7, 8, 55, 56, and so on.

                  Networks have a network address, and a broadcast address and a valid range (hence ‘broadcast domain’). If you have subnetted networks, then I SUPPOSE its ok to call them subnets… but I won’t call them that lol.

                    @Wayne-Workman Ok I am stuck using your example so I pulled a random IP from my high school.
                    Subnet mask: 255.255.0.0
                    IP: 10.2.1.64

                    Binary IP Subnet:

                    00001010.00000010.00000001.01000000
                    11111111.11111111.00000000.00000000

                    (Client IP network portion: 00001010.00000010.0000 Client portion: 0001.01000000)

                    Which the fall through for the network address if I am correct would be:
                    00001010.00000010.00000000.00000000
                    which give a network address of 10.2.0.0

                    After that I am not sure where to go as I get confused by what you did.

                      (only where there is a 1 for subnet, the IP address portion falls through)
                      Fall through: 00001010.00000010.00000000.00000000 <-- your network address

                      To get the broadcast, turn on all the client portion ‘bits’ where the subnet mask is 0.

                      00001010.00000010.11111111.11111111 <-- your broadcast address 10.2.255.255

                        @Wayne-Workman And that broadcast address should allow me to run the wake on lan to the high school which is where that IP came from?

                          It should. Test it and report back? I am not using the plugin yet so I don’t know, but if Tom says that’s how it is, then 99.9% of the time, that’s how it is.

                              You likely need to allow udp-broadcast-forwarding on your switches. At the very least, it needs to be enabled for the routing switch. The way to do this varies depending on the switch. HP Procurve allows for udp-broadcast-forwarding on (I think)

                                    @Tom-Elliott I worked with @Wayne-Workman and he helped me figure that out by converting an IP address into that. Previous posts go through it and thats what we came to the conclusion it is.

                                          @szecca1 are you 100% sure that 10.2.255.255 is that networks broadcast address?

                                          If the info he gave me is correct, I can assure that what we came up with is correct, but feel free to doublecheck my work using third party tools: http://www.subnetonline.com/pages/subnet-calculators/ip-subnet-calculator.php

                                          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!
