Hello Experts,

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

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

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.
