GNS3 ASA setup: Import and configure Cisco ASAv with GNS3 In this video I show you how to download, import and configure a Cisco ASA with GNS3. Free software worth $200: https://goo.gl/613TUF. There are many IOS images of different networks devices on the web, but some of them are the most used on GNS3, to do the networking exercises to practice or prepare CCNA, CCNA or even CCIE and real Labs of networking as if you were working with real network devices, since the images come with all the features supported, for example by a physical router or switch.

Cisco Firewall :: Migrating Netscreen Firewall To ASA 5515 Version 8.6?
Mar 5, 2013I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?
Cisco Firewall :: 5510 - Transparent Firewall Installation Using ASA Version 8.4(3)9
May 14, 2012 I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?

-IP of GNS3 PC on which GNS3 is installed. 192.168.1.102/24 default gateway of LAN: 192.168.1.1/24
I have created a loopback adapter and assigned the IP address of 192.168.1.200/24 (IP is also of same LAN) the cloud and virtual router is dragged and router interface is assigned the IP 192.168.1.201/24. I am able to ping my router interface from 192.168.1.102 (System on which GNS3 is installed). What I want is to ping my router's interface from other LAN PCs line 192.168.1.104, 192.168.105 or from my gateway 192.168.1.1.

Cisco Firewall :: Convert ASA 8.2 Version To 8.4?
Jun 17, 2012I try to convert a CISCO ASA 8.2 version to 8.4 BUT, I have a small or 'little' problem :On Cisco ASA 8.2.x, i have a possibility to create multi-line global with different subnet.Example :
global (outside) 2 217.1.x.65-217.x.x.66 netmask 255.255.255.240
global (outside) 1 interface <-- Ip interface is other subnet : 217.3.x.3
global (outside) 2 217.1.x.67 netmask 255.255.255.240
nat (inside) 1 0.0.0.0 0.0.0.0
nat (dmz2) 2 192.168.4.0 255.255.255.0
What is the method or solution to translate multi-global in 8.4 ? with static translation in 8.4 : i try to use different server in inside's zone, but not in same network on outside. In 8.2 Firmware, it's very easy to use that, but in 8.3-8.4 version, i don't have some idea to manipulate ...

Cisco Firewall :: LAN To LAN Between ASA5520 Version 8.3 And PIX?
Apr 19, 2011We have 2 firewalls on PIX facing the Internet and connected to interface e1 (behind it) an ASA version 8.3 Both the PIX (Firewall facing) and the ASA are on the same subnet.
By using Routing statements and statics I have been able to reroute specific traffic to the ASA5520 version 8.3 Now I need to inverse the 2 devices. The ASA5520 will be facing the Internet and the PIX will be behind it.Unfortunately the ASA5520 is refusing to route the traffic to the PIX. The access-lists are open accordingly and a NAT on the ASA has been created.

Cisco Firewall :: IP SLA Monitoring On ASA Version 7.0 (6)?
Dec 20, 2011how to configure ip sla monitoring on asa ver 7.0 (6) ?
In this blog post, I will demonstrate how to emulate CISCO ASA 8.4 firewall with GNS3 1.x and QEMU Emulator.
In this procedure, I’ll be using following Binary IOS images:
Get the required IOS Binary Images:
You may copy these from CISCO hardware ASA device using following commands:
# copy flash: tftp:
> provide file to send to TFTP Server
> provide tftp server’s ip here
> just press enter to copy with same name.
– Use same procedure for both Binary images.
Else, you may download from CISCO website using registered authorized account.
Unpack the IOS Images:
To use these Binary images with GNS3, we need to Unpack ASA IOS binary image “asa842-k8.bin”, I’ll use a script developed by a user “dmz” from 7200emu.hacki forum. You can download script from link given below:
Download repack.v4.sh
Cisco Ios Images
– Copy downloaded Script “repack.v4.sh.gz” and “asa842-k8.bin” binary IOS image to linux instance. I’ll be using CentOS 7.
# cd /usr/local/src
# gunzip repack.v4.sh.gz
# chmod +x repack.v4.sh
asa842-initrd-original.gz – original extracted initrd
asa842-initrd.gz – patched initrd
– Among these, we need
asa842-initrd.gz – patched initrd
– copy these two files to GNS3 Images Directory.
NOTE: If facing Error:
# ./repack.v4.sh asa842-k8.bin
Repack script version: 4
which: no xxd in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
which: no mkisofs in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
ERROR: xxd command not found
Solution: Install ‘vim’ or ‘vim-enhanced’ package to get it
# yum install vim -y
Configure GNS3 to use ASA Firewall in topologies:
“QEMU VMs” > “New”
Add:
– Name: Any Name for ASA device, I’ll give “ASA1”
– Select “ASA 8.4(2)” from Drop Down Menu.
– Browse “asa842-initrd.gz” file for “Initial RAM disk” option.
– Browse “asa842-vmlinuz” file for “Kernel Image” option.
– Create new topology, Drag ASA1 Icon to work space and make some topology, I’ll create topology for two ASA firewalls with on VirtualBox XP VM connected via Ethernet switch as shown below:
Add ASDM image to ASAs in topology:
– Start first ASA device.
– console it
– Assign IP to ASA interface of same network as of XP VMBox Instance, in my scenario, it is 10.0.0.0/24 network.
– just press enter when asked for “Password”, as there’s not set any.
# configure terminal
# show int ip brief //show present interfaces.
# interface g0 //I’ve connect g0 interface with switch.
# no shutdown
# ip address 10.0.0.1 255.255.255.0 //assign IP to g0 interface
# nameif inside //Assign this interface to “Inside” network of firewall.
– Copy ASDM into ASA firewall in GNS3:
# copy tftp: flash:
> provide tftp server ip, 10.0.0.5
> give file name to copy, asdm-645-206.bin
> just press enter to save with same filename.
– it will start copy.
# http server enable //Enable HTTP/S server.
# http 0 0 inside //Allow HTTP/S access from any host from Inside network interface.
– Just select “OK” when asked for user credentials, as we’ve not configured any user on ASA yet.
– Done,
