Cisco ASA stands for Cisco Adaptive Security Appliance.
Cisco ASA acts as both firewall and VPN device.
If you have upgraded from Windows 7/8 and need to install the Cisco VPN client then you can use the following instructions on how to cleanly install it or fix a bad install of it after upgrading to Windows 10. 7 Steps total Step 1: Uninstall Cisco VPN. May 29, 2019 Setting up Cisco AnyConnect VPN is similar to setting up any VPN client. The approach depends on the device you’re installing it onto but once installed, setup is very straightforward.
This article explains how to setup and configure high availability (failover) between two Cisco ASA devices.
On a production environment, it is highly recommended to implement two Cisco ASA firewall (or VPN) in high available mode. This way, if the primary ASA fails, the secondary becomes active automatically without any downtime.
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.
In the above diagram:
On the Cisco ASA 5520 model, it has 4 ports on the back, marked as 0, 1, 2 and 3. In our example, we’ll be using port 0, 1, and 3 as explained above.
Other than the 4 network ports, you’ll also see slots marked as mgmt, usb, usb, console, aux, flash card.
While the example mentioned here was done on Cisco ASA 5520 model, the same configurations will work on other Cisco ASA 5500 series. i.e Cisco ASA 5510, Cisco ASA 5505 etc.,
Line 6 others driver. Connect your laptop serial port to the primary ASA device using the console cable that came with the device.
Use PuTTY -> Select “Serial” -> Make sure serial line is set to “Com1” -> and speed is set to “9600”
Execute the following commands to mark the port 0/3 as failover lan unit primary.
Execute 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. This device should also know what is the failover ip-address of the standby. In this example, it is 10.10.1.2
You should also specify a failover key. Make sure the same key is used when you are configuring failover on the secondary device. In this example, the failover key is “secretkey”
Execute the following commands which will assign “174.121.83.47” (the one marked as ext0 in the diagram above) to the 0/0 interface on the primary device. This device should also know what is the external ip-address of the standby ASA device. In this example, it is 174.121.83.48
Execute the following commands which will assign “192.168.1.47” (the one marked as int0 in the diagram above) to the 0/1 interface on the primary device. This device should also know what is the internal ip-address of the standby ASA device. In this example, it is 192.168.1.48
Execute the following commands to verify the failover configuration that has been setup so far on the Cisco ASA primary device.
Connect your laptop serial port to the secondary ASA device using the console cable that came with the device.
Use putty -> Select “Serial” -> Make sure serial line is set to “Com1” -> and speed is set to “9600”
Execute the following commands to mark the port 0/3 as failover lan unit secondary Drivers micro data.
Execute the following commands which specifies the primary LANFAIL ip-address is 10.10.1.1 and standby is 10.10.1.2
You should also specify a failover key. Make sure the same key that you used while configuring primary ASA is used here also. In this example, the failover key is “secretkey”
On you configure the LANFAIL as shown above, all other configurations are automatically copied from the primary Cisco ASA device to the standby cisco ASA device.
Setup additional configurations on the Cisco ASA primary device as shown below. This includes, hostname setup, domain name setup, route setup, allow http and ssh on internal ip-address for the cisco ASA primary.
Leave it for blank driver download for windows. Note: All the above configuration will be copied over automatically to the Cisco ASA standby device, as the failover is already configured. The only thing you need to setup on Cisco ASA standby is the hostname as “FW-STANDBY” as shown below.
Finally, view the current running configuration, and write it to the memory as shown below.
Stanford's VPN allows you to connect to Stanford's network as if you were on campus, making access to restricted services possible. To connect to the VPN from your Windows computer you need to install the Cisco AnyConnect VPN client.
Two types of VPN are available:
You can select the type of VPN you want to use each time you connect to the Stanford Public VPN.
