I see lot of established connections to my apache server from the ip 188.241.114.22 which eventually causes apache to hang . After I restart the service everything works fine. I tried adding a rule in iptables

-A INPUT -s 188.241.114.22 -j DROP

but despite that I keep seeing connections from that IP. I'm using centOS and i'm adding the rule like thie:

iptables -A INPUT -s 188.241.114.22 -j DROP

Right afther that I save it using: service iptables save Here is the output of iptables -L -v ` Chain INPUT (policy ACCEPT 120K packets, 16M bytes)
