cara nak wat Firewall.......(^___^)

1. Pasang FW = iptables(install)=yum install iptables
2. Reset(rules) = Flash (all)
3. Default Rules = block (drop)
4. Allow

#/sbin/iptables-F
#/sbin/iptables-X
#/sbin/iptables-L
#/sbin/iptables-nvL

*check rules

#/sbin/iptables-P INPUT DROP
#/sbin/iptables-P OUTPUT DROP
#/sbin/iptables-P FORWARD DROP
#/sbin/iptables-nvL

nak allow web

-#iptables s-A input  -S <ip> -p TCP -dport 80 -J ACCEPT
