Make sure the same key is used when you are configuring failover on the secondary device. This device should also know what is the failover ip-address of the standby. Assign the failover ip-address on Primary ASA using LANFAILĮxecute the following commands which will assign “10.10.1.1” (the one marked as fail0 in the diagram above) to the 0/3 interface on the primary device.
#Cisco asa 5505 configuration example serial#
Use PuTTY -> Select “Serial” -> Make sure serial line is set to “Com1” -> and speed is set to “9600”Įxecute the following commands to mark the port 0/3 as failover lan unit primary. Setup failover interface on Primary ASAĬonnect your laptop serial port to the primary ASA device using the console cable that came with the device. While the example mentioned here was done on Cisco ASA 5520 model, the same configurations will work on other Cisco ASA 5500 series. Other than the 4 network ports, you’ll also see slots marked as mgmt, usb, usb, console, aux, flash card. In our example, we’ll be using port 0, 1, and 3 as explained above. On the Cisco ASA 5520 model, it has 4 ports on the back, marked as 0, 1, 2 and 3. fail3 indicates that this is connected to the port 3 on the device.

int1 – Assign your internal ip-address to this interface.ext0 indicates that this is connected to the port 0 on the device. ext0 – Assign your external ip-address to this interface.

The following diagram explains on a high-level the ip-address that are assigned to the primary and secondary cisco ASA devices in this example. This way, if the primary ASA fails, the secondary becomes active automatically without any downtime. On a production environment, it is highly recommended to implement two Cisco ASA firewall (or VPN) in high available mode.

This article explains how to setup and configure high availability (failover) between two Cisco ASA devices. Connect to the ASA > Go to enable mode > Go to configuration mode > Create a ‘vpdn’ group, (here I’ve called it PNL-DIALER-GROUP) > Set the authentication method, (here I’m using CHAP).Cisco ASA stands for Cisco Adaptive Security Appliance.Ĭisco ASA acts as both firewall and VPN device.

Before you attempt to configure the connection, you will need the following from your ISP
#Cisco asa 5505 configuration example password#
So without the need for a router, you can get the ASA to perform the authentication (supply the username and password via PPPoE) and either use a static IP address, or obtain its IP via DHCP. Here in the UK the main ISP’s ( BT and Virgin) are busy rolling out FTTC connections that terminate with a ‘modem’ that presents an RJ45 socket. A Router that connects via PPPoA usually. Most of my clients in that sort of connection speed range have ADSL with a router provided by their ISP. Until very recently I’d never had to configure PPPoE.
