How would I configure a "dumb" switch to broadcast all packets? (self.networking)

Hi, I'm looking at the dumb switches from TPLink, Netgear, Cisco etc - is there any way I could make them broadcast all packets that they are receiving?

The use case is that I want to mirror my WAN traffic without port-mirroring on the router. I was thinking that if I could just plug the incoming WAN connection into a switch, and then (if the switch could broadcast all traffic), take one port to the firewall, and the other port to a dedicated device for analysis.

Can this be done without having to change settings on my router/WAN connection?

Thanks!

Indeed, vendors stopped using the word Ethernet Hub. Keep in mind that Hubs were mostly 10Mbit, 100Mbit were rare. Would that be enough for you? I don't have a Hub model to suggest you, sorry. If speed is an issue, I would suggest reviews for some smart/unmanaged switches (<$25) might show options to convert it to Hub. Let's see if others use one and reply ;)

Thank you, I have not received any comments yet. Pity that I cannot convert the small 5-port TPLink/Netgear switches into hubs, would have been great. Thanks for your help
