Wanted to check if any one else is having this issue, I am working on enhancing my mail gateway fail2ban jail scripts and encountered an issue with a rule missing. I do not think it is related to my changes but you never know.
I boot my server, I have 6 jail configuration.
Output of iptables: (notice: --match-set f2b-sshd missing)
I reload: fail2ban-client
Output of iptables: (notice: --match-set f2b-sshd can now be found)
It appears to me that this occurs when we use the fail2ban action: iptables-ipset-proto6-allports in multiple jail activities such as: clearos-sshd.conf & clearos-sshd-ddos.conf
Anyone else noticed this problem?
