[Kiswono Prayogo]

yes, i use iptables.. hmm.. am i forgot to open some port that used by
dhcp? these are some of my default policies:

## clear all rules

iptables -F
iptables -X
iptables -Z

iptables -t filter -F
iptables -t filter -X
iptables -t filter -Z

iptables -t nat -F
iptables -t nat -X
iptables -t nat -Z

iptables -t mangle -F
iptables -t mangle -X
iptables -t mangle -Z

## default policy

iptables -P FORWARD DROP
#iptables -P FORWARD ACCEPT
iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT

## allow localhost

iptables -A INPUT -i lo -j ACCEPT

## allow some ports

iptables -A INPUT -p TCP --dport  80 -j ACCEPT # http
iptables -A INPUT -p TCP --dport 443 -j ACCEPT # https
iptables -A INPUT -p TCP --dport  53 -j ACCEPT # dns
iptables -A INPUT -p TCP --dport 123 -j ACCEPT # ntp
iptables -A INPUT -p UDP --dport  53 -j ACCEPT # dns
iptables -A INPUT -p UDP --dport 123 -j ACCEPT # ntp
iptables -A INPUT -p ICMP -j ACCEPT
iptables -A INPUT -p GRE -j ACCEPT

#... many others forwarding policies

iptables -A POSTROUTING -t nat -o $ee -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
