Boa tarde a todos, como mencionei sou novo no linux, tem uns 6 meses que migrei para o linux, de agora em diante uso servidores linux. Enfim...Instalei squid 2.7 stable 9 no Debian 6 pra roda em modo transparent, o squid esta operando, ja adicionei as regras do iptables, eu nao consigo fazer nat, abaixo segue as configurações da rede, squid.conf e rc.local:
Minhas configurações de rede são as seguintes, uso classe para ip tipo C, 192.168.0.0, GW 192.168.0.1
etho entra a internet
eth1 rede externa #eu necessito da nat para uma classe ip diferente#
Haveria possibilidade de roda um servidor proxy enviando endereçamento IP por DHCP.
Desculpe os possiveis erros, estou aprendendo e fazendo um cursinho ja.
