using fail2ban for years, working nice, would like to automate and harden the security for my router.
So I would like that fail2ban created a local file, example, list.txt file with a list of banned IP addresses.
Something similar to this https://sslbl.abuse.ch/blacklist/sslipblacklist.txt
So I could share it on a webpage. My router is set up to import blocked IPs from such sources.
So how could I manage to do something like that? Any ideas?
