Boa tarde pessoal,
Fiz a instalação do squid.
Quando coloco no meu navegador a proxy 10.1.1.250:3128 (ip da maquina).
Não consigo acessar nenhuma pagina da web.

Segue meu arquivo conf.

#
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https

acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT


# Regras pessonalizadas
acl macs_liberados arp "/etc/squid/macs-liberados"


#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed

http_access allow macs_liberados

http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320




Agradeço pela ajuda.

esse não é o script firewall com regras iptables, provavelmente deve ser algum front-end do iptables. Certo ?

Em caso afirmativo, qual front-end ?

tu tem a regra de redirecionar da porta 80 para 3128 ?

sugiro ao invés de utilizar front-end do iptables, usar iptables puro em um script shell.

Saiba como fazer em: http://goo.gl/pQRtk

No Squid:
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
#acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
#acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
#acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
#acl localnet src fc00::/7 # RFC 4193 local private network range
#acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

Comenta todas as regras como acima.
a tua rede é 10.1.1.0
Cria uma acl assim: acl localnet src 10.1.1.0/24 << se a tua máscara de subrede for 255.255.255.0

E coloca "transparent" depois de http_port 3128 se teu Squid for versão 3.0, 2.7 ou 2.6 e "intercept" se teu Squid for versão 3.1 ou acima.

No IPtables deixa como coloquei acima, somente muda a eth+ para a placa de rede de entrada da internet e na regra do redirecionamento coloca a ethx que saí para a sua rede interna.
