Hi All,
I believe I understand from this post how to setup a blackhole NAT to block unwanted IPs however what I'm not sure about is if I need to create a unique definition for every IP I want to block or if there's an easier way. I have already blocked Russia and China but didn't really want to block the entire world.
As a comparison, I also have a Synology NAS which has a great feature where it automatically permanently blocks an IP for LIFE after X number of failed attempts within Y minutes. I can then choose to remove this blocked IP from the block list if it is a legitimate one. Does Sophos offer a similar feature that is that easy to setup? If it does, I haven't found it.
