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:
I also think that It could be hardware related? not sure
Thank you for helping
