A firewall generally works at layer 3 and 4 of the OSI model. Layer 3 is the Network Layer where IP works and Layer 4 is the Transport Layer, where TCP and UDP function.
Many firewalls today have advanced up the OSI layers and can even understand Layer 7 - the Application Layer.

What is transparent firewall?
Since the fundamental task of a firewall is to filter packets, the weak point in its traditional behavior is the fact that it also must route packets after a decision is made. Can the model be simplified? Of course it can, and the answer comes by stepping down a layer in the OSI model. Instead of the device handling packets at layer 3 (network), what if it merely inspected frames and moved them to the proper interface? Sound familiar? This type of device would continue to filter packets, but operate at layer 2 (data link), like a bridge. Such a device has come to be known by several names: a transparent, in-line, shadow, stealth or bridging firewall. ranajoy karmakar@gmail.com ccna,network engineer
