This forum is only for reproducible bugs with csf and lfd (i.e. not iptables problems, lack of understanding how to use a feature, etc). Posts must be accompanied with full technical details of the problem and how it can be recreated. Any posts not adhering to this, or not considered bugs, will be moved to the General Discussion (csf) forum.
I noticed that when CSF bans an IP temporarily, it's not checking for duplicate IPs. So, in the screen for "Show Banned IPs", I see duplicate IPs. I have also verified that these same IPs are blocked in the IPTABLE for multiple times as well (which consumes more resources).
