How do you connect to your server from outside or inside?
this my config
EXTIF="eth0"
INTIF="eth1"
$IPTABLES -P INPUT DROP
$IPTABLES -P FORWARD ACCEPT
$IPTABLES -P OUTPUT ACCEPT
#Allow related and established on all interfaces (input)
$IPTABLES -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
#Allow releated, established and ssh on $EXTIF. Reject everything else.
$IPTABLES -A INPUT -i $EXTIF -p tcp -m tcp --dport 22 --syn -j ACCEPT
$IPTABLES -A INPUT -i $EXTIF -p tcp -m tcp --dport 80 --syn -j ACCEPT
$IPTABLES -A INPUT -i $EXTIF -j REJECT
#Allow related and established from $INTIF. Drop everything else.
$IPTABLES -A INPUT -i $INTIF -j DROP
#Allow http and https on other interfaces (input).
#This is only needed if authentication server is on same server as chilli
$IPTABLES -A INPUT -p tcp -m tcp --dport 80 --syn -j ACCEPT
some thing like this....
