The idea I've is to write a translate application that translates pfsense backups to cyberoam format to restore from there, this should do at least 80% of the job, from there I'm sure some polishing will remain but it
I've worked before with Pfsense, but not with with cyberoam, but they are all very similar on how they work internally, with some more or less features.
If you have a large set of rules, the core here is just to get the right format translator but I'd really like to have some expression of interest before I start working on it.
However if the number of firewall rules is small (<100) it could be better just to do them manually and take the opportunity to see if optimizations can be done.
