Despite setting the ignoreip value to the IP of our network, it would seem that fail2ban is ignoring this config and still bans us when multiple people access the server via SSH. The ignore list has been set in both jail.conf and jail.local with no success.
Is there another setting which switches on/off the ignoreip feature?
Edit:
Further to sr_'s comment, I'd include the jail.conf contents but there really isn't anything to share; all I've done is appended our IP after ignoreip = 127.0.0.1 as outlined in the documentation.
ignoreipvalue and/or the context of yourjail.conf. You could also tryfail2ban-client get <JAIL> ignoreipto get insights. – sr_ Dec 10 '12 at 13:02
