Nao compartilha a internet

Galera hoje de manha estava com muitos problemas aqui voltar o meu squid apos uma atualizacao acabei colocando ele para funcionar so que ele nao esta fazendo o compartilhamento da internet para a rede internet.

ALguem teria uma luz pois estou trabalhando nisto desde de cedo sem parar e ja to enchergando tudo embaralhado ja rs,

Vlw

Pra vc habilitar a rede interna pra acessa a internet:

# echo 1 > /proc/sys/net/ipv4/ip_forward
# iptables -t nat -A POSTROUTING -o eth0 -p tcp -j MASQUERADE

Obs.: no lugar do "-o eth0", vc pode colocar a rede, ex.: "-s 192.168.1.0/24".

Opa,


Da uma olhada ve se tem algo errado

A versao do squid 3.0

Verifiquei sim o problema parece estar no arquivo S90Firewall dentro da pasta /etc/rc.d05

A internet travou apos atualizar a bosta do fedora.

Poizé... pelas msgs q foram mostradas e pela informação d q vc atualizou a "bosta do Fedora" (iuhaihaiuah, ri muito...), é q ele ativou (ou reativou) o Firewall nativo dele com as regras d segurança. Dae vc deve desativar o firewall dele em Administração > Firewall ou por linha d comando. Acredito q seja assim:

# chkconfig --list iptables

Pra saber quais são os níveis q ele está sendo ativado. Vamos supor q seja 2,3,4 e 5, desative-o dessa forma:

# chkconfig --level 2345 iptables off

Reinicie seu sistema.

AMigo,

Pior que nao o firewall nativo ja estava desabilitado.
nao sei o que pode ser vc teria msn

GALERA HELP AI !

Você adicionou a regra que ativa o roteamento no kernel ?

#echo 1 > /proc/sys/net/ipv4/ip_forward
