Dear Victor,

I still receive traffic from that ip.......


IPTABLES Rules
#iptables -I INPUT 1 -s 202.145.10.147 -j DROP

IPTRAF Monitoring
??202.145.10.147:1668                                                    =
31           19815     DONE       eth0       ?
??202.46.146.164:25                                                      =
33            1485     CLOSED     eth0       ?
??206.190.39.164:8

I try :
#iptables -I INPUT 1 -s 202.145.10.147 -j LOG
after that ip show again :
#iptables -L -nvx
