Liberar o outlook no firewall

[andrecharamos]

Galera!

Estou com problemas com firewall para libera o outlook, eu tinha conseguido mas andei alterando algumas coisas ai bloqueou novamente, nao sei oque eu fiz de errado,

Outra duvida, e que no servidor firewall eu consigo pingar nos sites externos ex:www.google.com.br mas nas estações eu nao consigo, eu consigo somente na rede interna, ou seja nas estaçoes eu nao consigo pingar em www.google.com.br. nao sei se tem alguma coisa a ver com o meu problema
segue o script do firewall

#!/bin/bash

Por acaso foi depois que você adicionou:

$IPTABLES -A INPUT -p tcp -s 10.1.1.0/8 -d 201.76.49.33 --dport 110 -j ACCEPT
$IPTABLES -A INPUT -p tcp -s 10.1.1.0/8 -d 201.76.49.33 --dport 25 -j ACCEPT

$IPTABLES -A OUTPUT -p tcp -s 10.1.1.0/8 -d 201.76.49.33 --dport 110 -j ACCEPT
$IPTABLES -A OUTPUT -p tcp -s 10.1.1.0/8 -d 201.76.49.33 --dport 25 -j ACCEPT
