Boa tarde senhores,

Estou precisando tirar algumas duvidas referente ao squid, segue abaixo:

Tenho 2 ips:
eth0 192.168.1.250 mask 255.255.255.0 gt 192.168.1.254 (rede local)
eth1 192.168.0.250 mask 255.255.255.0 gt 0.0.0.0 (modem)

no Firewall estou usando a seguinte regra:

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.250:3128

sudo modprobe iptable_nat
sudo modprobe ip_nat_ftp
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

Mais as regras do squid não estao funcionando, segue abaixo o squid.conf

Olá Tiago, por favor entenda como uma crítica construtiva, o seu squid.conf está muito confuso, as acls estão trabalhando contra você, e não para você. Eu tentaria simplificar, acredito que até mesmo para quem criou essas regras está muito dificil depurar.

Tiago, tem umas coisas erradas na sua configuração. Mas para te dizer como deve ficar me responda

Como está organizada sua rede? o diagrama dela é esse?

Internet-Modem---->>>Firewall-Squid----->>>RedeLocal


Se for, porquê você tem um gateway no endereço da rede local?
Você usa dois gateways com balanceamento de link?
Que máquina é essa que tem o ip 192.168.1.254?

Valeu pessoal, vou dar uma reduzida nessas acls, valeu mesmo.


Minha rede esta funcionando da seguinte maneira:

Modem ------- Firewall/Squid (192.168.1.250 - Internet / 192.168.0.250 - Redelocal) ------ Redelocal (192.168.0.0/24)

Dei uma melhorada no squid e esta funcionando corretamente, segue abaixo. o meu problema agora é com o Firewall:

Tenho 2 ips:
eth0 192.168.1.250 mask 255.255.255.0 gt 192.168.1.254 (modem)
eth1 192.168.0.250 mask 255.255.255.0 gt 0.0.0.0 (rede local)

no Firewall estou usando a seguinte regra:

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.250:3128

sudo modprobe iptable_nat
sudo modprobe ip_nat_ftp
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

mais a rede local esta dando como acesso negado, sera que alguem pode me ajudar com o firewall

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.250:3128

Tiago, não sei pq você está fazendo DNAT aqui, se você não tem um motivo pra isso então sugiro que remova a regra acima do seu firewall (pode simplesmente comentar).


sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

Aqui você está invertendo as coisas (interfaces), pois a interface de entrada é a da rede local e a de saída a da internet, então corrija e deixe assim:

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128

Pronto, agora os problemas que você enfrentar (se tiver) devem ser de squid

Você colocou a eth0 como -o (out-interface) e a eth1 como -i (in-interface)?
A chain POSTROUTING não aceita -i e do mesmo modo a PREROUTING não aceita -o
http://focalinux.cipsga.org.br/guia/avancado/ch-fw-iptables.html#s-fw-iptables-outras

A mensagem de acesso negado não está sendo do squid? você pode postar um print da tela do erro?
