Alterar IP do Firewall [RESOLVIDO]

Esqueci de dizer, o firewall tem 2 placas de rede, eth0 e eth1, como faço para saber qual e qual?

[root@mail ~]# ifconfig

Olha o comando ifconfig, agora instalei o putty, fica mais facil mostrar como ta aqui

A eth0 é sua wan. A eth1 é sua lan.

É a eth0 que você precisa modificar.

exiting.

Blz, agora acima ta o comando dhcpd -d, ta mostrando o ip antigo.

Olha como ficou com o route modificado

Bom, agora deu certo, consegui acessar a net usando passando pelo fire, mas agora o Zimbra nao funciona, da o seguinte erro:

Host mail.meudominio.com.br
Starting ldap...Done.
Failed.
Failed to start slapd. Attempting debug start to determine error.
daemon: bind(7) failed errno=99 (Cannot assign requested address)
slap_open_listener: failed on ldap://mail.meudominio.com.br:389


lembrando que meudominio foi alterado para evitar problemas =D




Outra coisa, percebi um detalhe qual a diferença entre IAPDDR pra HAWDDR? la nas config do eth0 pede o seguinte:

IAPDDR= o meu ip fixo valido correto?
GATEWAY= qual ip q coloco aqui? o meu gw ou oq?

Ok, funcionou as trocas (vi que tua tabela de roteamento estava faltando a default da eth0. Acho que arrumaste).

Agora tu deves estar tendo problemas com DNS. Verifique seus DNS's. O arquivo ao qual o servidor "busca" o DNS é o resolv.conf (em RH like, normalmente no /etc/resolv.conf)

Ele esta buscando estes ips:

192.168.0.6
8.8.8.8
4.2.2.2

eth0 esta assim agora:


DEVICE=eth0
BOOTPROTO=none
HWADDR=00:20:ed:6e:xx:xx
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=201.62.48.xxx
GATEWAY=192.168.0.252



preciso colocar essa aqui?


NETWORK=192.168.0.14


vc nao tem facebook pra gente resolver isso mais rapido nao =D
