CISCO error Dialer

Hi,

I have got a perfectly working router cisco 850. (router#1)
I have backed up the configuration file successfully.

I also have another 850 (router#2) from which I have loaded the working configuration of router#1.

The issue is that some errors appear on router#2 & it is not working accordingly.
(example: no working internet connection)

I have noticed these 2 errors when starting router#2

%NAT: Error activating CNBAR on the interface Vlan1
%NAT: Error activating CNBAR on the interface Dialer1

The question is why the working configuration of router#1 not working on router#2?

If that can be of any help, the flash file of the routers are:

Router#1: c850-advsecurityk9-mz.124-15.T7.bin
Router#2: c850-advsecurityk9-mz.124-6.T6.bin

I also think that It could be hardware related? not sure

Thank you for helping

Router#1: c850-advsecurityk9-mz.124-15.T7.bin
Router#2: c850-advsecurityk9-mz.124-6.T6.bin

Your firmware is different.

Try installing the same firmware on router 2 and see what happens first.

Check your flash drive...

Type "dir" and it will show you available space and what files are there.

You can delete unused files.

Infamus ,

as you see :

ip route 0.0.0.0 0.0.0.0 Dialer1 ( this route belong to ATM interface )

so i think if he do no shutdown command for dot11radio0 interface , this will not effect .

Thanks

Your issue was resolved by installing the same firmware and ATM error is basically because it was administratively shut down.

i don't think that was the answer to the original issue.

Hi Infamus,

Sorry for late reply.

to confirm how the issue was solved, I re-installed the c850-advsecurityk9-mz.124-6.T6.bin on router#2

I then re-installed the running conf of router#1 on router#2. Of course at this point it is still not working.

I then run the ATM no shut on router#2 & this resolved the issue.

So installing the same firmware didnt fix anything. The no shut command did.

Thank you again for your help, but my accepted solution is correct

Regards
