Novamente to recorrendo a vocês, instalei o squid3 e configurei corretamente o proxy transparente, porém não consigo fazer o bendito funcionar, somente navega com proxy atribuido no navegador, se retirar já não navega mais, por favor preciso muito disso e não consigo fazer funcionar de maneira alguma...abraço galera!!!!!
