Due to a recent issue withim360 we noticed IM360 firewall is not using iptables, instead is injecting rules into memory without saving them, so if the IM360 service fail and iptables doesnt fail to start, youll be locked out until imunify360 does. So please re think to use iptables in your firewall. We was using CSF before....we removed CSF and installed IM360, someone could think this action will clean all the blocking rules in the process...well no, looks like after we have uninstalled CSF and installed IM360 and probably restarted Im360 a lot of times....iptable old rules never were cleaned...we noticed this months after when an ip was being blocked without any logic reason. Thanx!
