I'm sure this is a 101 question, but I honestly am not sure of the answer. Will network broadcast traffic jump interfaces on a Cisco ASA 5510?

Allow me to attempt to describe the network:

Sonicwall NSA 250
Inside Interface IP: 192.168.1.XX
Outside Interface IP: 74.XX.XX.180

Cisco ASA 5510
Inside Interface IP: 10.4.XX.XX
Inside2 Interface IP: 192.168.1.XX
Outside Interface: 74.XX.XX.181

Both the Sonicwall and the Cisco devices are connected to a cable internet modem on the outside interfaces

Both the Sonicwall and the Cisco devices connect to the LAN through a Cisco switch on the Inside interfaces

The Cisco Interface Inside2 connects to a Netgear switch and a separate LAN

Traffic passes from the 192.168.1.XX network to the 10.4.XX.XX network in both directions.
Both LAN can access the internet

So... my question is... will broadcast traffic from 192.168.1.XX pass to the 10.4.XX.XX network?

Now, I didn't mentioned any ACLs on either device because I was wondering if the break in segments would be sufficient to stop broadcast traffic.

Thanks for all comments and advice

The answer to that question is no. Broadcast traffic from any device within a subnet will only broadcast within that same subnet.

Perfect... that's the answer I expected, but for some reason I needed to confirm.
