Yeah, I realized that from the above. I mean I was a happy camper with my regular backups, all nice and tidy, indexed by date and name, safely stored on the server. So if a router goes up in flames I got exactly squat. Nice…
Trying to import firewall configuration and get an error:
Import file-name=firewall.rsc
failure: already have such entry
What does this mean?  Firewall and nat empty.

Apart from the fact that you are misusing another topic:
- Export the current config
- Compare it to the one you are trying to import
This is what you say…
Without showing us the current “/ip firewall export” and without showing us the firewall.rsc that you expect, are we guessing?
(a list in the Address List cannot have two identical IPs)
And as already written by @erlinden open your topic when the problem is the misuse of something…
Thanks.  Actually,  I figured out.  Evidently, I was not looking in the all tabs.  ADDRESSES were still there.  So, once I deleted them, the import took place normally.  Thank ypu
