I don't understand why it doesn't  send this warnings/errors to log 
file? I think that it would be the correct behaviour, don't you think?
The only info that I see in the log file is:
"Mar 07 09:40:36 ** Restarting Arno's Iptables Firewall v2.0.1a **
Mar 07 09:40:46 ** All firewall rules applied **
Mar 07 09:49:04 ** Restarting Arno's Iptables Firewall v2.0.1a **
Mar 07 09:49:05 ** All firewall rules applied **
Mar 17 22:38:14 ** Restarting Arno's Iptables Firewall v2.0.1b **
Mar 17 22:38:24 ** All firewall rules applied **
Mar 22 04:32:22 ** Starting Arno's Iptables Firewall v2.0.1b **
Mar 22 04:32:44 ** All firewall rules applied **
...."
