turma,

preciso bloquear msn por ip, tipo so alguns usuários deverão acessar o bate-papo.

segue meu fire e squid.

fire.

#!/bin/bash

#interface da internet:
#ifinternet="eth1"

#interface da rede:
#ifrede="eth0"

iniciar(){
modprobe iptable_nat
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A INPUT -p icmp --icmp-type echo-request -j DROP
echo 1 > /proc/sys/net/ipv4/conf/default/rp_filter
iptables -A INPUT -m state --state INVALID -j DROP
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -i eth1 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -p tcp --syn -j DROP
iptables -I FORWARD -s "10.0.0.0" -p tcp --dport 1863 -j DROP
