Is there any way to perform a factory reset of a Mikrotik via UI and not lose the ability to access it remotely?
I mean a way for MK to add automatically after resetting a firewall rule

You could reset and have the device run an initial script.
The config.rsc must be stored in the /flash folder. Details can be found here: https://wiki.mikrotik.com/wiki/Manual:C ... tion_Reset

If you have lots of devices with that issue then perhaps this is something that can be solved by dude, or something similiar.....
