Ola amigos tenho um server 2008 com duas placas de rede, uma recebe  internet e outra distribui para a rede 192.168.1.0/24, bem como os serviços de dhcp, dns, ad, etc. Estou tentando instalar o squid proxy porém  os computadores da rede dizem que não podem se conectar ao proxy, segue meu arquivo squid.conf

acl to_localhost dst 127.0.0.0/8
acl rede_escopo src 192.168.1.0/24
