Hello Experts,

An Expert provided me with the following link to show me how to successfully simulate a Cisco ASA on GNS3


http://www.network-blog.com/ittech/post/2011/11/16/How-to-set-up-Cisco-ASA-firewall-8x-on-GNS3.aspx

Everything was working fine until I tried to assign an IP address to the gigabitethernet interfaces.

I think the problem is that I need to type in the information in step 4, but I don't know where I actually type it.

modprobe e1000
ifconfig eth0 hw ether 00:00:AB:CD:10:10
ifconfig eth1 hw ether 00:00:AB:CD:10:11
ifconfig eth2 hw ether 00:00:AB:CD:10:12
ifconfig eth3 hw ether 00:00:AB:CD:10:13
ifconfig eth4 hw ether 00:00:AB:CD:10:14
ifconfig eth5 hw ether 00:00:AB:CD:10:15
ifconfig eth0 up
ifconfig eth1 up
ifconfig eth2 up
ifconfig eth3 up
ifconfig eth4 up
ifconfig eth5 up
cp /asa/bin/lina /mnt/disk0/lina
cp /asa/bin/lina_monitor /mnt/disk0/lina_monitor
cd /mnt/disk0
/mnt/disk0/lina_monitor

I think the problem is that you can't assign IP address to gigabit ethernet interfaces, which may explain why I need to add step 4 - but I don't know where/how to type the information?

OK, the problem is I don't know how to get the option to configure an IP Address on an ASA.

I know the procedures to configure an ip address, I just don't know how to get the option to configure an ip adddress.

I have two ASA's running, ASA1 & ASA2. I can configure an ip address on the interface on ASA2 but can't on ASA1.

I thought it had something to do with the 'mode' I was in , but when I chnaged to system mode I still don't get the option to configure an IP address to the interface.

I should mention that I'm running ASA1 in multiple mode and ASA2 in single mode.

Any help would be greatly appreciated.

Cheers

Carlton

@cpatte7372,
Once you have configured the ASA files in QEMU, drag the ASA Firewall from the left panel to the center.

Then right click on the ASA Firewall youhave just dragged and click on "Start". Once it started right click again ande click on Console. It would open the console probably a black window with nothing in it untill to hit enter once or twice, from there on follow the steps listed in step 4.

I have just done those configuration and there are no issues.
