Is there a Layer 2 firewall?

Is there a Layer 2 firewall?

A transparent firewall, also known as a bridge firewall, is a Layer 2 application that installs easily into an existing network without modifying the Internet Protocol (IP) address.

Can you configure a Layer 2 firewall?

You can configure Layer 2 Firewalls in Passive Firewall mode. In Passive Firewall mode, the engine captures network traffic for inspection but does not actively filter traffic. Normal Interfaces are used for communication between the Layer 2 Firewall and the Management Server.

How does a Layer 2 firewall work?

A Layer 2 transparent firewall operates on bridged packets and is enabled on a pair of locally-switched Ethernet ports. Embedded IP packets forwarded through these ports are inspected similar to normal IP packets in a routing network.

What is Cisco ASA transparent mode?

Key Characteristics of ASA Firewall When Configured In Transparent Mode – Transparent firewall mode supports only two interfaces (inside and outside) The firewall bridges packets from one VLAN to the other instead of routing them. MAC lookups are performed instead of routing table lookups.

What is Layer 7 firewall?

What is a Layer 7 Firewall? A layer 7 firewall, as the name suggests, is a type of firewall that operates on the OSI model’s 7 layers. The seventh layer of the OSI model, often known as the application layer, allows for more advanced traffic-filtering rules.

What is Layer 2 configuration?

You can configure Layer 2 switching ports as access or trunk ports. Trunks carry the traffic of multiple VLANs over a single link and allow you to extend VLANs across an entire network. All Layer 2 switching ports maintain MAC address tables.

What is transparent mode?

Transparent mode converts the firewall device from its default layer 3 route mode to what is essentially a layer 2 bridge. Once all interfaces have been converted to the layer 2 zones, the device is considered to be in transparent mode.

What are three characteristics of ASA transparent mode?

What are three characteristics of ASA transparent mode? (Choose three.)

  • The interfaces of the ASA separate Layer 3 networks and require IP addresses in different subnets.
  • This mode is referred to as a “bump in the wire.”
  • This mode does not support VPNs, QoS, or DHCP Relay.
  • It is the traditional firewall deployment mode.
