As I'm still pondering (in another thread) why csf won't block an IP at all and actually miscategorizes it as IPV6, here's another email sent that appears to have issues identifying the IPs in question:
Ah, you're right, my apologies. Sleep deprivation. This arrived right after a "blocked with too many connections" email generated by CSF. I'm on my wits' end here
i am wondering if my issue comes under this tree as a couple of days back i was getting UDP requests from an IP however the IP was clearly blocked. By the way is the csf supports IPV6?
