Question
Create New Network with Cisco Packet Tracer 4.1
Can some one help me to create this in Packet Tracer Ver. 4.11 files and document?
1) Containing basic network (without ACLs) files.
2) Containing the network with ACLs applied files.
3) Document in working with an explanation for the subnet plan and the access control lists.
Network devices should be fully configured with a naming convention used to identify all devices in your network.
Please refer to the attached file for more detail.

Packet Tracer should be able to handle the ACLs just fine, of course the best free "simulator" around is GNS3 (www.gns3.net) if your able to get your hands on a real IOS image. As for ACL Editor it can be purchased here http://www.garethevans.inf
What do you have done so far?
Thanks. Here is it.

I am sorry the forum won't allow me to upload. I put a link for you to download from my FTP server.
Many thanks.
I'll leave the rest and what interfaces to add the ACLs to in your capable hands.

IT MNT
ip access-list standard IT->Management
permit 141.70.48.0 0.0.0.255
Thanks for your help. I just try again to set the router connect the IT and Management as below:
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#access-list
Router(config)#exit
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface GigabitEthernet0/0
Router(config-if)#
Router(config-if)#exit
Router(config)#interface GigabitEthernet0/0
Router(config-if)#ip access-group 1 in
Router(config-if)#exit
Router(config)#
Router(config)#interface GigabitEthernet1/0
Router(config-if)#ip access-group 1 out
Router(config-if)#exit
Router(config)#
And I try to ping from IT host to Management host and it still give the result as below:
Packet Tracer PC Command Line 1.0
PC>ping 141.79.64.1
Pinging 141.79.64.1 with 32 bytes of data:

Ping statistics for 141.79.64.1:

I don't know where I did wrong and why it keep no reply. I has been try for few days and can't make it work until today my due date and I still try to work it out. Can you tell me why it doesn't work? Can you help me to configure some of ther router in the pkt file so I can try to understand from there.
Thanks.
Here is the config I get from the router.

I feel like I miss out some part of the setup in the router. Rounting setup?? Static & RIP ?? Can you help to make this router work in my packet tracer file and give it to me? I almost give up now.
Sorry no. I still work on it. I can't make the ACL function. If I apply the gateway, it will allow to ping both way in Management and IT. Then I implement the ACL that you give to me at "interface GigabitEthernet1/0" as outbound. It make no different. When I try to insert and access-list deny from Management to IT "interface GigabitEthernet0/0 then block the ping both way in the LAN. I was try it until 4am in the morning and give up. It make me go crazy.
Thanks. Here is it.
Packet Tracer 4.1 program download.

Packet Tracer File

Please tell me is there any problem on physical connectivity. Router setting RIP/Static and so on.
Some of the problems I found with your network.
No connectivity. All serial links were up/down because no clock rate was configured on the DCE, done with clock rate 64000
Incorrect IP address was used, everything used a mask of 255.255.240.0 when you were asked to use variable subnetting for each segment.
RIP was also incorrectly configured. Version 2 should have been used because of the variable subnet requirements. Also split horizon needed to be disabled on all the WAN router's serial interfaces since RIP by default will not send updates out to the spoke routers otherwise.
Lastly your ACL placement was incorrect, you tend to use both in/out directions on the same interface, careful planning is needed to know what kind of affect this would cause.
If I have time tonight 'll fix up the pkt file so you can see how it looks.
I also have a couple recommendations for when you post another question on the site to improve your success.
If you need assistance in another assignment, please clearly state in the question that it is homework and what exactly you need a hand with as well as what you have tried rather then just posting the question requirements. Experts will be more likely to assist you if you make it clear that your trying to understand a problem rather then get some experts to do your homework. Also if the deadline is add the date to the question and possibly raise the point value of the question so we can better gauge the urgency.
Lastly, you have rated yourself a guru on the subject, but have said you don't have much experience with Cisco. This can mislead the experts and effect the level of help you receive. Since to us it looks like you have a firm understanding of the topic and requires minimal explaination to get you going.
