How to limit broadcast traffic to two PC's

[joriseveraert]

We have a hardware appliance that behaves badly on the network.  It constantly sends broadcasts on port 45454 to announce its presence on the network.  We have only two possible clients for this appliance, on the same VLAN as the appliance. What is the best solution please to make sure that the traffic only reaches the intended receivers ?

What if we move the two PC's to another VLAN ?

As they are broadcasts, your best option is pretty much what you've already mentioned, moving the devices to their own VLAN (you mention moving the two recipients, but you also want to move the source host too).

Please go for a  private vlan...if you want the 2 pc's to communicate with each other..(community vlan)..no communication needed (isolated vlan)
