Hi,
I have a RH8 and planning to make it a DNS Server, but I have problem using the iptables. Here is my configurations for my firewall
IPTABLES=/sbin/iptables
LAN="208.108.143.90"
$IPTABLES -P INPUT DROP
$IPTABLES -F INPUT
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -F OUTPUT
$IPTABLES -P FORWARD DROP
$IPTABLES -F FORWARD
$IPTABLES -A INPUT -i lo -j ACCEPT
$IPTABLES -A INPUT -d $LAN -p tcp --dport 80 -j ACCEPT
LAN="208.108.143.90"
$IPTABLES -P INPUT DROP
$IPTABLES -F INPUT
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -F OUTPUT
$IPTABLES -P FORWARD DROP
$IPTABLES -F FORWARD
$IPTABLES -A INPUT -i lo -j ACCEPT
$IPTABLES -A INPUT -d $LAN -p tcp --dport 80 -j ACCEPT
$IPTABLES -A INPUT -d $LAN -p tcp --dport 53 -j ACCEPT
$IPTABLES -A INPUT -d $LAN -p icmp -j ACCEPT
$IPTABLES -A OUTPUT -o lo -j ACCEPT
$IPTABLES -A INPUT -d $LAN -p icmp -j ACCEPT
$IPTABLES -A OUTPUT -o lo -j ACCEPT
When I use this as my firewall I cannot ping any website using their URL (ie www.yahoo.com). What is lacking with my configuration to make a firewall for my DNS Server?
TIA
Wesley
