Open Terminal then open the TftpServer.app with superuser privilege. Once the connection between ASA and tap1 interface is up.

On GNS3, console to ASA and give it an IP address that is in the same subnet as the tap1 interface. Verify the tap1’s IP address NetworkShinobi-MacBook-Air:~ networkshinobi$ ifconfig tap1 On the Terminal, type-in: NetworkShinobi-MacBook-Air:~ networkshinobi$ sudo ifconfig tap1 10.1.1.2/24 up Giving the tap1 interface an IP address will allow it to connect to the ASA on GNS3. NetworkShinobi-MacBook-Air:~ networkshinobi$ ifconfig NetworkShinobi-MacBook-Air:~ networkshinobi$Īfter Entering the /dev/tap1 on GNS3, the system created a tap1 interface.

Inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 As you can see there is no tap1 interface. Here is the ifconfig before I entered the /devt/tap1 on GNS3. Here is the before and after screenshot of my ifconfig This will create another interface on your Mac. Drag an ASA, generic switch, and a cloud to the canvas as seen in Figure 1. This is will open GNS3 with superuser privilege. NetworkShinobi-MacBook-Air:~ networkshinobi$ sudo /Applications/GNS3.app/Contents/MacOS/GNS3

Now, open your Terminal and open GNS3 with superuser privilege.

The TunTap project provides kernel extensions for Mac OS X that allow to create virtual network interfaces. Here is a brief description what a TunTap is. The files are asa842-initrd.gz and asa842-vmlinuz.ĭownload ASDM version that is compatible with 8.4(2) from using your CCO account. Now, that you have installed GNS3, you would need two files to make the ASA to work on GNS3.

Download GNS3 if you have not done so, and install it.
