liberar portas servidor squid(Resolvido)

[mgottfried]

estou com o seguinte problema:
instalei um servidor squid em uma rede da seguinte forma:
adsl -> squid eth1 + eth0-> server2008 e rede local
ja liberei a porta 3389 do adsl para eth1 192.168.254.10 onde entra o sinal de internet para a rede , como faço para liberar esta porta para o ip do server2008 = 192.168.1.100.
a eth0 do servidor squid é ip 192.168.1.1.

iptables -t nat -A PREROUTING -p tcp --dport 3128 3389 -j DNAT --to 192.168.1.100:3389
iptables -A FORWARD -p tcp -d 192.168.1.100 --dport 3389 -j ACCEPT

[mgottfried]

rejeitou a conexão

Essas regras têm que ser encaixadas no seu firewall --- se é que vc tem um.

[mgottfried]

coloquei as regras no final mas ainda continuo sem acesso.

[zekkerj]

Erro meu: coloquei "--dport 3128", deveria ser "--dport 3389". Já corrigi lá em cima.

[mgottfried]

ainda continua negando acesso , na rede interna o server2008 esta recebendo TS.

[zekkerj]

Vc observou se o primeiro redirecionamento está funcionando?

[mgottfried]

o proxy esta direcionado para a porta 3128.

[mgottfried]

    #iptables -A INPUT -p tcp –destination-port 3389 -j ACCEPT


    #iptables -t nat -A PREROUTING -i eth1 -p tcp –dport 3389 -j DNAT –to-destination 192.168.0.100:3389

    #iptables -A FORWARD -p tcp -i eth1 –dport -d 192.168.0.100 -j ACCEPT

coloquei esta regra mas volta o erro
