Packet Tracer Lab Troubleshooting

Hello,

I apologize in advance if this is the wrong community. I'm working on a lab for a course and need some assistance with troubleshooting in Packet Tracer. There are supposedly two things wrong with the Packet Tracer configuration and I cannot seem to figure it out. I've attached an image of the instructions and the topology. Below is the information associated with each device:

PC IPv4 Address: 44.1.1.10, Subnet Mask 255.255.255.0, Default Gateway 44.1.1.1

Interface Fa0/0 Router 1 IPv4 Address: 44.1.1.1, Subnet Mask 255.255.255.0 (44.1.1.2)

Interface Fa0/1 Router 1 IPv4 Address: 69.0.0.14, Subnet Mask 255.255.255.248

Interface Fa0/0 Router 2 IPv4 Address: 44.2.2.1, Subnet Mask 255.255.255.0 (44.2.2.2)

Interface Fa0/1 Router 2 IPv4 Address: 69.0.0.13, Subnet Mask 255.255.255.248

Web Server Default Gateway: 44.2.2.1

Web Server Fa0/0 Interface IPv4 Address: 44.2.2.10, Subnet Mask 255.255.255.0

Hello @justindabear 

Few things wrong in your PT project.

Start with Sw1:

Int fa0/2 facing router R1 has to be in a Trunk mode ! 

-Configure fa0/2 like this:

M02rt37_0-1700515599277.png

Then go to R1, interface fa0/0 facing SW1 ; it should be a sub-interface, called Router On A Stick https://www.packettracerlab.com/router-on-a-stick-configuration/

M02rt37_1-1700515747725.png

 

Now PC should ping its gateway, hosted in R1:

On R1, modify your static route. Next hop is wrong! Next-hop should be interface fa 0/1 of R2, 69.0.0.013 not 69.0.0.12.

On R1 static route should be:

On Router R2 now, same way, configure Router On a Stick on Fa0/0, facing Sw2 ; like this:

On Sw2, modify Fa0/2, and configure Trunk mode:

Server should ping its gateway:

PC should ping Server:

Hello- please see attached. 

Hello,

 

A couple things I would check:

1. Are the IP addresses of the interfaces (and masks) exactly as they are supposed to be from the diagram and instructions?

2. Is there routing configured? i.e. does R1 know how to reach the LAN network of R2 and vice versa?

3. Are there any ACLs blocking the traffic you need to reach the server configured and applied to any interfaces along the path?

As M02@rt37 mentioned a PT file would be helpful. What you supplied was not the PT file (from what i could see)
