If we need to allow traffic initialized from host connected to the outside interface (level 0) to enter the interfaces with a higher level (100 or 50, in our case), we have to configure an access-list (ACL).

For this reason traffic initialized behind the outside interface is passed neither to the inside nor to the server interfaces. However traffic initialized from the interface with a lower security level is not passed to the interface with a higher security level. In general, traffic initialized from the interface with a higher security level is allowed to enter the interface with a lower security level and back. In this case, network traffic takes a path from the server interface (level 50) to the outside (level 0) interface and back. The same is valid for traffic sent from DC to the Internet. Thanks to the security levels concept, TCP and UDP traffic from the hosts connected to the inside interfaces (level 100) can reach hosts in DC, behind the server interfaces (level 50) or hosts in the Internet behind the outside interface (level 0). The link connecting the ASAv-I to the vIOS-EDGE-I router is configured with the interface name OUTSIDE and it has assigned a security level 0. The links connecting ASAv-I to the DC are configured with the interface name SERVER0 and SERVER1. The links connecting ASAv-I to the Core switches are configured with the interface name INSIDE0 and INSIDE1. # copy disk0:/coredumpinfo/coredump.cfg disk0:/use_ttyS0Īs a first step we configure the hostname. Then reboot the ASAv and you should be able to manage ASAv via GNS3 console afterwards. When ASAv boots up, copy the file coredump.cfg to a disk0 in a privileged exec mode (password is not set).

Therefore we need to redirect vASA output to a serial port. However we want to use GNS3 console instead of Qemu console. Once we start ASAv, the Qemu window is launched. Note: Here is the configuration file of vASA-I. Similarly, the second connected interface eth2 is referred as the GigabitEthernet0/1 and so on. The first connected interface is then the interface eth1 that is referred as the interface GigabitEthernet0/0 in ASAv CLI. The interface eth0 is not connected as we use the inside interfaces for management instead. Note: The interface eth0 on the ASAv-I is referred as the interface Management0/0 in ASAv configuration.

In order to lower memory consumption, GNS3 is configured to assign 1536 MB to the ASAv. Note: The recommended RAM size for ASAv instance is 2048 MB. Picture 1 - ASAv-I, Campus, DC and Edge Connection It also connects the campus network and DC to the vIOS-EDGE-I edge router. The ASAv-I provides traffic filtering and inspection services for the campus network and Data Center (DC). The device is a Cisco Adaptive Security Virtual Appliance (ASAv) version 9.6(1) installed on qcow2 Qemu disk. The article explains configuration of the device ASAv-I.
