GNS3 – How to communicate with Pemu
Posted by Josh on Wed 23 Apr 2008Categories: Cisco , GNS3 , PEMU - [50] Comments
In this tutorial, you will learn how to connect an MS Loopback interface on your PC to the PEMU Pix emulator using GNS3. The trick is to use a switch between the cloud and the virtual PIX.
The same theory works to connect your virtual PIX to a physical interface on your PC. I have successfully created a lab that allows me to connect to the inside interface of the PIX to the loopback interface and the outside interface to a physical interface on my PC.
Maybe I will create a tutorial for the above scenario. Stay tuned.

thanks so much will give a try

Great as usual, Josh.
I may try to get this running on an old box to simulate a PIX in a real network.

What about cisco webvpn (ssl VPN) video soon? Thanks

Todendi,
If you have an ASA firewall, I would like to do a tutorial on SSL VPN with the new AnyConnect Client.
I have installed it on an ASA and it is very nice.
The problem is that it only runs on ASA ver 8.0 and on an ASA firewall and not a pix. Pemu does not emulate an ASA (only a Pix). I have not been able to get ver 8.0 to run with pemu.

What kind of software do you use to create this wonderful video? Thanks,
May 1st, 2008 at 11:18 pm
I used Camtasia Studio for this video. I have also used Wink in the past.

[...] Since I discovered Dynamips and Pemu, I have been trying to figure out a way to test Pix configurations with a single PC running Windows XP. The real trick has always been communicating with the virtual Pix. With Linux, it was not a problem but Windows has always been another story until I recently figured out how to communicate with pemu using GNS3. [...]

I am having problem saving the topology. The network consist one cloud, one switch, and a PIX. Everything is working fine (can telnet to the PIX from my PC) but if I saved the network and re-launch the .net file. The switch will no longer there and the cloud will no longer work. I have to re-create another cloud and put in a switch again. I have this error when I tried to save the network. “KeyError: u’localhost:7200′. Can someone help?

Thanks Josh, yeah I still have that problem.

I am new to PEMU and GNS3 and I need some guidance on the basic setup for PIX.
When I setup the PEMU PIX information (i.e. path, SN, KeyCode), I receive a PEMU error ‘…Pemu cannot start on port 10525…’ as soon as I place the PIX icon in the workspace. I am running MS Vista and using PIX 7.24
Any help would be appreciated.

No matter what i do, i am unable to ping the inside interface of the PIX in PEMU, the outside interface works fine, When i connect the cloud to the router, i can ping the router from my PC, but not the PIX.
I have used the switch, so thats not the problem.
i have connected two PIX using switches parallely, i can mutually ping their outside interfaces but, not the inside interfaces.
Could anyone suggest a solution.

Hi
Im facing all kinds of strange problems with PEMU, i have connected a PC’s loopback interface to a switch and then to a PIX, the PIX is then connected to the router, i can ping the firewall outside from the router and vice versa
this image represents the setup, ignore the second PIX
http://i342.photobucket.com/albums/o410/vj_v1/test1.jpg
The problem is i am not able to ping the PIX from the PC, the loopback interface etc are fine, when i ping from the PIX to the pc and simultaneously from the PC to the PIX, i get the ping every now and then. this seems somewhat strange,

Could anyone suggest a solution
Thanks in advance
July 13th, 2008 at 1:44 am
@Vj,
Could it be an ARP issue between the loopback interface and the PIX? Maybe try connecting the pix to your ethernet interface instead of the loopback.
Use arp -a to see arp resolution on the PC and show arp on the firewall.
Josh
July 13th, 2008 at 8:08 am
Thankyou for the reply
arp appears to be fine but the problem still persists.

Hi ALl,
do i need PIX IOS for implementing the firewall network.If yes which IOS is recommended..
August 1st, 2008 at 2:44 am
Hi,,
I am not able to ping the PIX from PC(Vice-versa).But i m learning the MAC-Address of both the interfaces..
I hope u can resovle the issue..Waiting for ur repsonce..

Haris,
Thanks!
Josh

Akshay,
Use the following command to enable telnet to an inside ip address.
telnet 0 0 inside
You will need software specifically for the Pix. The Pix does not run IOS.
Also, watch this tutorial. It may answer some of your questions.

nwachonky,
Try this:
If you do not need a license key, skip step 1.
1) Search google and ebay for show version output of a Pix firewall with an unrestricted license.
http://www.blindhog.net/gns3-how-to-find-pix-images-pix-serial-numbers-and-ios-images-using-google/
2) Set the default serial number of Pix firewalls in GNS3 to match the serial number of the output you found on ebay or google.
3) Boot the virtual firewall
4) Enter the activation key from the CLI
5) Save the GNS3 topology as a project.

Hi
I am new to PEMU and GNS3 and I need some guidance on the basic setup for PIX.
I am able to set up the PIX with OS 7.2.4 and able to telnet to it. The problem is the cloud that I cannot configure. I can’t choose an adaptor to be associated. I have install MS loopback and configured the LAN and Loopback IP. I have also bridge these 2 adapters. Is there something else I need to do? I am however using Vista, don’t know if it can be an issue? Please help. Thanks.

hey guys,I have configured SSL VPN on an 1800 router.I can connect to almost everything except my outlook is not working,not connecting,and I can’t connect to the server as well,authentication keeps failing…is it because I’m authenticating locally on the router?please help..

Hi guys,
The software is excellent for pix. But I am unable !#@$!#$ to save a topology, or the configuration when I setup a cloud to connect to the pix from my pc. I run windows XP with GNS3. Any ideas? I get the following error when saving…….

Hi I am using gns3.7 the latest release and I dont know wahts happeneing but 2 problems I am facing with.
1. I dont see any loopback interface on my windows pc (I hate windows but have to use it no choice)
2. Since there is Qemu other than Pemu, PIX is not allowed to connect to the switch.
Kindly let me know what should I do to fix this.
March 17th, 2010 at 6:38 pm
Zeeshan follow this
1–> just restart your pc and loopback will come up, it happened to me.
2–>I am using GNS3.07, no issue as such, i upload asa7.2 image to pix and valid serial and activation (license) key. I implemented above lab without any problem.
hope it helps
For those who have communication issue with inside interface, hope you have given ip address in same subnet of your loopback interface…
August 10th, 2010 at 10:30 pm
This comment is about your video about connecting Pix to real internet. Do you have to have static IP addresses from your ISP?Where do you get the ip address for outside interface on ASA?
I have loopback 172.16.1.1/24 gateway 172.16.1.15 connected to inside 172.16.1.15/24 and they can ping eachother. I have outside connected to physical NIC. I loose connectivity to internet when I remove GW from it. I assign that gateway to outside int and assign it ip one less than the NIC ip like you do in the video, but it does not work. What am I missing?
Thanks.
August 11th, 2010 at 11:29 am
Moody,
The post was setup in a lab environment behind a firewall/nat router. If you want to connect directly to an ISP, you will need to do things a bit.
Josh
September 26th, 2010 at 9:49 pm
Thanks Josh
I finally got it to work by sharing my physical NIC with loopback, which assigned IP 192.168.0.1 to loopback. I assigned 192.168.0.2 to ASA outside and I can ping the internet now. I connected ASA inside to another loopback and connected a virtual XP to it, I can surf the net on virtual XP through the ASA. Just wanted to share in case someone wanted to try it out.

could you please let us know how to run ASA 8.2 in GNS3 ?

Suhail,
There is a way to test vpns between VMWare and GNS3. There are several tutorials on this site to help connect virtual machines to GNS3.
What host OS are you using for VMWare?

Hi,
Having same problem as you Eitan. Have VirtualBox running WinXPSP3-32 bit and can’t seem to find out how to ping loopback (10.1.1.2) from my virtual ASA (IP 10.1.1.1). Keep getting back ????.
Guess I’m close. Any help would be really appreciated!
