When a Cisco ASA is run in transparent mode, am I correct in thinking that all layer 2 broadcast traffic is allowed through the firewall? Does this not leave the chance that viruses / malicious code could be broadcast through to end systems??<br />
<br />
Thanks.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation.
