Hi All, I am running Ubuntu Server 14.04 in the "Perfect Server" configuration, and I noticed that fail2ban is not actually working. Did some research and found that I had to turn on the firewall (ufw enable). Great - except that it blocks everything now. I confess that iptables is one of those things which I don't understand :-( At the moment, I would be happy to have everything pass the firewall (it has been since the server was built) except for the IP addresses banned by fail2ban I have tried to find a how-to related to this, but with no success. I am guessing that I have to put something somewhere in the INPUT chain, but I am not sure. Can anyone assist in a configuration for this.
