The guys at GNS3.net have done it again! They just released version .04 of their incredible network emulation software. There are lots of new features including Pemu integration, c1700 and WICs Support and Project feature (you can keep router configs, nvram …).
Here is a full list of the new features:
- A dynamic mode (no design/emulation modes)
- A new .net save/load.
- c1700 and WICS support.
- PIX emulation.
- Dynamips’s ATM bridge.
- Capture feature for links from the GUI.
- IDLE PC calculation from the GUI.
- GUI improvements (save the window state when closing GNS3 …)
- Annotation feature.
- Project feature (you can keep router configs, nvram …)
- NULL NIO support.
- PDF export.
- New languages.
I would like to challenge everyone to make a donation to one of the projects below. Don’t worry if you can’t donate a lot. If everyone would donate the amount they tipped the waitress at their last dinner out, I am sure it would make a huge difference to the people writing the code.
http://www.dynagen.org
http://www.gns3.net
If you are in charge of the pemu or dynamips projects, please let me know. I would like to add you to this list.

Oh, yeah. That’s good stuff.
I can’t wait to give it a shot at home (where I actually have rights to install stuff).

Hello Josh,
Thanks for the video
Certinly helps a lot.
Please help me out with a query
I see that you are using the PIX IMAGE 7.2(3) can i use the PIX 6.3(5).
In PEMU i point the IMAGE to PIX6.3(5) and provide with the KEY and the SERIAL number, However i am unable to connect. Kindly Help me.
March 26th, 2008 at 9:01 am
I will try it this evening.

Awesome Josh.
I appreciate your quick response.

I tried to use 7.0.2 image and it didn’t work.
March 26th, 2008 at 2:29 pm
shef,
Do you get an error? Try to start the firewall and console in immediately after.
Josh
March 26th, 2008 at 11:31 pm
Allen,
I tried a 6.3.5 image and you are right, it did not work right for me either. I will try to look into it more.
Josh
March 26th, 2008 at 11:46 pm
Allen,
I think I figured it out. I had to use the serial number and activation code from an existing PIX running 6.3 software.
You can get both with the show version command.

Shef,
Version 7.0.2 may have the same problem. Please try this and report your results.

Hello,
Thank you for wonderul tutorials. Just wanted to ask few queries :-
a) The version 6.x isnt working for PIX in GNS, the instance will never connect or stop.
b) The version 7.x works fine, but lot of CPU hog.
c) The 3des/failover key activation process is missing in windows version of GNS3 with PEMU support.
d) Idlepc can not be set manually as it says already set !! whats going on in thi .4 release ?
thanks
March 27th, 2008 at 2:26 am
Rajiv,
a) With the 6.x software, you are probably having the same problem as Allen. I had to configure the serial number and activation code from a running pix firewall to get a 6.3(5) image to work. Go to Edit > Preferences > PEMU to set this.
b) This behavior is not uncommon.
c) Check Edit > Preferences > PEMU for these settings.
d) As far as I know, there is not an idlepc setting for PEMU. If you are talking about the routers, that has been moved to the GUI. Right click on the router and select ‘IDLEPC’

Hello Josh,
Thanks for your help
I tried again with PIX 6.3(5)entering the serial number and the activation code from a running pix firewall with no luck, however i tried using the 6.3(3)and it works just fine.
Any advice Josh.
March 27th, 2008 at 9:11 am
Not really. I am not sure why it is not working for you. You might try posting on the hacki forums.

Please has anybody been able to connect network interface cards to pix firewall in GNS3, it says it cannot connect devices. If we can’t connect devices the why are they there.

Hi
I saw the tutorial. I did same as you mentioned in the video
I just would like to know can I use this IOS emulation to connect with my real network and utilize it as real firewall.

I have downloaded the new release of GNS3, same as with release 4 i am having hard time simulating the PIX, but the router is fine..
Thank you.

ho i tried gns3 0.5 on both xp and vista and when i tried to connect to console it says the system can t specify the location of the this file how can i solve this problem please help
May 10th, 2008 at 1:04 am
@Wasnik,
What are you having problems with specifically?
@Michael,
The problem is that telnet.exe cannot be found. Follow This tutorial to use putty for console access instead of telnet.

May 13th, 2008 at 12:21 am
Sir,
I follow the tutorial, but I use the relase 5, from your GNS3 release 4 tutorial you use PIX 723, in my installation I use PIX 721.. after I load the image and start the device I wasn’t able to console the said device…
do I have to input the serial number for the PIX 721? can you provide link where I can download the PIX 723 image? Hope you can have this information..
Thank you and regards..
May 13th, 2008 at 1:44 am
I have image for PIX 724, hope you can provide serial number and activation key for this.
thank you.
May 14th, 2008 at 8:51 am
When using GNS3, the application used for console access is normally basic telnet. Personally, I do not like the windows telnet application at all. It does not allow logging or the ability to maximize the window.
so how can i use putty…….

Hello Josh
Do you have a NET file to simulate a PIX 6.3(5) lab.
I have tried to simulate a PIX 6.3(5) lab however i am unable to ping a router that is directly connected to the Inside interface.
Kindly help me.
.
May 31st, 2008 at 8:39 pm
@Allen, Try placing a switch between the router and pix. This was the only way I have been able to connect my PC to a virtual pix.
Here are a couple links that might help also.

Hello Josh,
Was a great Tuterioal Thaks
I am able to do this using the PIX7.x image
Unable to do the same using the PIX 6.3.(5)
Do you have a CONFIG file and NET file for a similar lab
I am trying to set up the following
VPC–>PIX 6.3(5)–>Router–Router–>PIX 6.3(5)–>VPC
My whole intention is to be able to PING from the VPC to the directly connected FIREWALL INSIDE interface
And From the Firewall OUTSIDE INTERFACE to PING to the directly connected interfac of the Outside Router
Thanking you in advance.
I am using the latest GNS3

I connected the pix and the router together with a switch and can’t ping the switch inside interface from the router pls help me
out!!!!!!!
June 11th, 2008 at 7:48 pm
Pings from the inside hosts to the inside interface does not work for me either. I have tried a few options such as
-Reinstalling GNS 30.5 beta
-Using IOS ver 723 & 802
-Installing a switch between the pix > inside router.
-Tried different IOS’es on the router.
NOTHING seems to get it to work. I wish there was a workaround. BTW, I am using GNS on Vista.
June 11th, 2008 at 11:53 pm
@Allen / @Kola / @AM,
In regards to the ping problems…I am not sure what this could be. Are you all three running Vista?
Here are a few steps to try:
1) Try ‘logging enable’, ‘logging mon 7′,’debug icmp trace’ and ‘term mon’ just to see if the packets are getting to the Pix.
2) Try the following commands in config mode:
icmp permit any echo-reply outside
icmp permit any echo outside
icmp permit any echo inside
icmp permit any echo-reply inside

I have just installed gns3. It’s look like very nice tools! I tried to figure out PIX. I have issue to figure IPsec/ISAKMP. I have download it IOS version 7.2(4) but i need licence. Can someone here help me whith that?
June 12th, 2008 at 8:18 pm
Josh,
I have tried all these options. Management-access inside is enabled.
One more thing, I have a friend who is using the same version of (GNS 3.5 beta)I configured a pix and router. The router could successfully ping the inside interface on Pix !!!!! He is also running vista just like me. We even have the same brand and model of laptop!!! Strange but true. I cant understand what could possibly be wrong with my configuration.
Here is a report from my laptop(ping does not work):
pixfirewall# ping inside 192.168.10.2

@AM - Please send output of ’show arp’ on pix and router after ping attempts.
Also, you might try placing a switch between the PIX and router…. http://www.blindhog.net/gns3-how-to-communicate-with-pemu/

I have tried with and without the switch between the PIX and Router. FYI, as mentioned in my earlier post, I tried the same scenario on my colleagues laptop and it worked WITHOUT the switch!!!! Please see output from my PC below
