Option For Asav Gns3
This is the fourth from the of the articles that discuss configuration of the enterprise network. The article explains configuration of the device ASAv-I. The device is a Cisco Adaptive Security Virtual Appliance (ASAv) version 9.6(1) installed on qcow2 Qemu disk.
The ASAv-I provides traffic filtering and inspection services for the campus network and Data Center (DC). It also connects the campus network and DC to the vIOS-EDGE-I edge router.Picture 1 - ASAv-I, Campus, DC and Edge ConnectionNote: The recommended RAM size for ASAv instance is 2048 MB. In order to lower memory consumption, GNS3 is configured to assign 1536 MB to the ASAv.Note: The interface eth0 on the ASAv-I is referred as the interface Management0/0 in ASAv configuration. The interface eth0 is not connected as we use the inside interfaces for management instead. The first connected interface is then the interface eth1 that is referred as the interface GigabitEthernet0/0 in ASAv CLI.
Similarly, the second connected interface eth2 is referred as the GigabitEthernet0/1 and so on.Note: Here is the configuration file of. ASAv-I ConfigurationOnce we start ASAv, the Qemu window is launched. However we want to use GNS3 console instead of Qemu console. Therefore we need to redirect vASA output to a serial port. When ASAv boots up, copy the file coredump.cfg to a disk0 in a privileged exec mode (password is not set). Then reboot the ASAv and you should be able to manage ASAv via GNS3 console afterwards.# copy disk0:/coredumpinfo/coredump.cfg disk0:/usettyS0As a first step we configure the hostname.ciscoasa enciscoasa# conf tciscoasa(config)# hostname ASAv-I1. Interfaces ConfigurationThe links connecting ASAv-I to the Core switches are configured with the interface name INSIDE0 and INSIDE1. They have assigned a security level 100.
The links connecting ASAv-I to the DC are configured with the interface name SERVER0 and SERVER1. They have assigned a security level 50. 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.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 same is valid for traffic sent from DC to the Internet. In this case, network traffic takes a path from the server interface (level 50) to the outside (level 0) interface and back.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. However traffic initialized from the interface with a lower security level is not passed to the interface with a higher security level. For this reason traffic initialized behind the outside interface is passed neither to the inside nor to the server interfaces.
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). The ACL must explicitly allow particular network traffic (e.g. How to register winrar. I have divided the network in two parts (2 computers):Network in computer 1: Data center, ASA, vIOS-Edge and ISPsNetwork in computer 2: CampusMy network worked well on a single computer, but now that I've divided it, it does not work.I have GNS3 over linux for both. I used two cloud appliances to connect the computers, that is, connect the network 172.16.0.8 for a network interface, and the network 172.16.0.12 for another network interface.
I use gns3 over linux in both computers. In the configuration of the cloud appliance I have only selected the interface where I made the connection and to that interface I assigned the corresponding IP address.
For example: In my computer 1 I have a network interface that corresponds to the G0/0 output of ASA, therefore, I assigned the IP address 172.16.0.13 to that interface.I did a ping test from vlan40 (PC4) to the ip 172.16.0.9 and to 172.16.0.13.

All I remember is that it was a pain to get it working, but that might have changed.i didnt expect it to be so damned difficult, it is a pain on the ass, i spent 3 days trying just to get it work but all my effort were useless, i tried also EVE Emulator but also it is confusing and difficult, i hope i can find a way to emulate a couple of ASA and Switchesanyway thanks for the link but again GNS3 documentation always direct you to buy IOS images from CISCO, it is just commercials no useful information.
