My Cisco RV180W has a corrupt configuration which is breaking the user interface in a few places. After a factory reset, it's fine - but if I restore my previous configuration it breaks again.
The backed-up configuration (.cfg) files are text files, and ideally I would like to restore parts of my old configuration (e.g. firewall rules, VPN users) by editing my 'clean' configuration file. However, the files contain a checksum line in the format:
... and if this checksum doesn't match the file contents, the router refuses to restore the file.
Does anyone know how I can recalculate this checksum after making manual changes to the configuration file?
