Hi strange behaviour of iptables on a centos 7.0 machine: The following rule is in the iptables of said machine: [root at myserver ~]# iptables -L -v -n --line-numbers |grep 175\. 9 9 456 DROP all -- * * 175.44.0.0/16 0.0.0.0/0 [root at myserver ~]# The corresponding enty in /etc/sysconfig/iptables looks like: [root at myserver ~]# grep 175 /etc/sysconfig/iptables -A INPUT -s 175.44.0.0/16 -j DROP [root at myserver ~]# The rule must be there since ages, because it has number 9 out of 76 similar rules. Today, on the same machine (I rechecked it to make sure not to confound machines), I see the following extract of the ftplog: <snip> 175.44.4.127 2915 175.44.26.128 2021 175.44.26.138 1322 175.44.6.186 1290 175.44.24.88 1219 175.44.4.199 1212 </snip> saying that from this IP addresse there have been this many connections to the ftp server on that machine during the last two days, which means that the iptables haven't dropped the connection to the machine. As far as I know, the ftp server is behind the iptables. I also checked to see in man iptables, wheather the IP address is represented correctly. What im I missing? thanks in advance suomi
