In which 2 modes does Asa work How are the 2 modes different?
ASA can perform static routing, Default routing also dynamic routing protocols like EIGRP, OSPF, and RIP. ASA can operate in two modes: Routed mode: In this mode, ASA acts like a layer 3 device (router hop) and needs to have two different IP addresses (means two different subnets) on its interface.
What is transparent mode Cisco?
The Transparent Cisco IOS Firewall feature allows users to “drop” a Cisco IOS Firewall in front of their existing network without changing the statically defined IP addresses of their network-connected devices.
What is transparent ASA?
A transparent firewall is a layer 2 firewall that acts like a stealth firewall and is not seen as a router hop between connected devices. Bridge groups are used to achieve layer 2 connectivity, where interfaces are grouped together, and the ASA uses bridging techniques to pass traffic between the interfaces.
What is ASA transparent mode?
Overview. An ASA Firewall is capable of operating at Layer 2 when running in transparent mode. This allows it to be installed into the network with minimal distruption becaue no IP addressing changes are needed on the network.
What are two features of transparent firewall mode?
Transparent Firewalls
- QoS.
- DHCP relay. Cannot be a DHCP server but can pass relay commands with extended ACL.
- VPN termination. only site-to-site VPN for management is supported.
- Extended ACLs can pass connections. SSL VPN is not supported.
- Dynamic/Multicast Routing. Need ACL to pass traffic.
- Dynamic DNS.
