Hello,

We are notice that the IPtables rules and Whitelist rules are not keep in configuration after a reboot, one of our customers Public IP is getting banned immediately after the server starts. We must delete the block rule from the IPtables chain (f2b-postfix) and added it manually in order to get access from customer IP, even that the public IP was added in the fail2ban jail.conf as a trusted IP.

Also we modified the file iptables-config in /etc/sysconfig and change the following parameters:

================================================================
# Save current firewall rules on stop.
#   Value: yes|no,  default: no
# Saves all firewall rules to /etc/sysconfig/iptables if firewall gets stopped
# (e.g. on system shutdown).
IPTABLES_SAVE_ON_STOP="yes"

# Save current firewall rules on restart.
#   Value: yes|no,  default: no
# Saves all firewall rules to /etc/sysconfig/iptables if firewall gets
# restarted.
IPTABLES_SAVE_ON_RESTART="yes"
=================================================

Thanks in advance for the help you can provide us.

Regards,
