Unable to backup switch

[Eelliiseen]

I need to copy running-config from R1, R2, S1, and S2 to PC-B with tftp. It works fine for every device, except for S1. I am able to ping PC-B from S1, but I am unable to ping S1 from PC-B.

Any help is appreciated

Thank you

you need to post the Sw1 config and tell us what is the PC-B IP address?  

along with post more IP information you have configured or any high-level diagram.

I have added the instructions and the File

Hello,

acually, if you are doing this in Packet Tracer, post the zipped project (.pkt) file.

I have updated my post with the zip file and instructions

Hello,

what are the passwords ? The ones in the instruction file don't work...

[Eelliiseen]

The passwords in the document should work fine. 

ciscoconpass

ciscoenpass

Username: admin Password: admin1pass

Hello,

your router R1 needs to announce network 192.168.1.0/24, for R2 to be able to reach that network. I have add the network in OSPF in the attached file.

I tested your file, but it did not work

Hello,

On R1, add:

router ospf 1

network 192.168.1.0 0.0.0.255 area 0

That should allow PC-B to reach S1.

But that one is already added

Hello,

this is from your original post:

-->  It works fine for every device, except for S1. I am able to ping PC-B from S1, but I am unable to ping S1 from PC-B.

Can you now ping S1 from PC-B ?

[Eelliiseen]

Thanks!

Yes, I can ping it now but I still can't do

copy running-config tftp 10.67.1.50

(Backup to PC-B)

Hello,

the NAT is the problem. On R1, add the following:

ip nat inside source list 101 interface GigabitEthernet0/0/0 overload
!
access-list 101 deny udp host 192.168.1.2 any eq tftp

See file attached.

Yes, we recently boticed the NAT was the problem. I haven't tried your commands yet but they don't seem to meet the requirements for our instructions. What does "access-list 101 deny udp host 192.168.1.2 any eq tftp" do exactly?
