Fail2Ban adds iptable rules but they are not working?
- by EApubs
Fail2Ban just blocked my IP for 3 SSH attempts. It added the iptables rule and I can see it using the "sudo iptables -L -n" command. But I can still access the site and login through SSH! What might be the problem? Is it because im using CloudFlare? I have set Nginx to write the real IPs to the access logs instead of the Cloud Flare IP. Isn't it enough?
