I have setup PSAD on my server. It asks me to add the following iptables rules:

Code:
iptables -A INPUT -j LOG
iptables -A FORWARD -j LOG
ip6tables -A INPUT -j LOG
ip6tables -A FORWARD -j LOG
I'm using UFW to manage iptables. So, I simply ran the command sudo ufw logging on But, whenever I restart PSAD or restart my server, I get an email saying:

message subject : [psad-status] firewall setup warning on server!

[-] You may just need to add a default logging rule to the /sbin/iptables
    'filter' 'INPUT' chain on *server*.  For more information,
    see the file "FW_HELP" in the psad sources directory or visit:
