Allowing Broadcast (either LAN or Global)

Argo

I have an SG135 that I would like to allow Broadcast for certain devices.

how do I accomplish this?

I have tried

Source Devices -> Any Service -> Broadcast Address (255.255.255.255/255.255.255.255 or a.b.c.255)

neither have worked as I still see broadcast traffic is being dropped.

I do realize that the UTM is meant to drop broadcast traffic, but I have read about ways to allow this traffic.

Any help appreciated.

    I always thought that a broadcast went to very IP in the sender's subnet and that the UTM just dropped the packet sent to it.  Isn't that what's happening?

    Hi Bob,

    yep, you're right.

    I can get the LAN Broadcast to be allowed but am unable to find a way to get the Global Broadcast to be allowed inside the UTM.

    well that's not entirely true, there are 5 Global Broadcasts being transmitted, only one is allowed (e.g. it is going green) the other five are dropped automatically.

    ** I may need to learn about global broadcasts, as I think I am missing something obvious to do with global broadcasting.

     

    thanks for you response
