Pessoal, tenho um cenário peculiar/bizarro aqui. Se ficar ruim de visualizar este e-mail (por causa da quebra de linha) vocês podem ver usando o endereço: http://www.mii.com.br/dois_ip_pppoe.txt
Primeiramente: meu provedor trabalha com PPPoE. Eu precisava de dois IPS, então conversei com meu provedor e eles me forneceram dois IPS, e disseram para eu fazer a seguinte configuração: <ISP> ---- <RADIO> --- <UM_UNICO_CABO_DE_REDE> --- <SWITCH> --- <CABO_DE_REDE> --- <MEU_FIREWALL_BSD> ......................................................................................................................|___<OUTRO_COMPUTADOR> Deste modo funciona tudo que preciso, - o <MEU_FIREWALL_BSD> utiliza o usuário [EMAIL PROTECTED] e obtem o ip 189.75.73.60 - o <OUTRO_COMPUTADOR> utiliza o usuário [EMAIL PROTECTED] e obtem o ip 189.75.73.30 - conseguem navegar na internet, tudo normal. Entretanto eu queria que os dois ips ficassem no firewall, e este redirecionasse para o <OUTRO_COMPUTADOR>. Fazer o redirecionamento eu consigo sem problema algum (já fiz isso quando eu tinha dois ips fornecidos, não por PPPoE e sim, fixados na NIC) O meu problema é justamente o PPPoE eu tentei dois cenários de configuração e nos dois acontece o mesmo problema: - consigo fazer a discagem da primeira conexão PPPoE com sucesso, tudo funciona com ela. - Quando vou fazer a segunda discagem aparece a seguinte mensagem no /var/log/ppp.log Apr 26 10:42:35 mt ppp[1519]: tun2: Warning: iface add: ioctl(SIOCAIFADDR, 189.75.73.30 -> 189.75.73.1): File exists Apr 26 10:42:35 mt ppp[1519]: tun2: Error: ipcp_InterfaceUp: unable to set ip address (o log completo está no final deste e-mail, meu ppp.conf também está no fim do email...) (a conexão [EMAIL PROTECTED] aparece como tun1 e [EMAIL PROTECTED] como tun2, pois eu já tenho a tun0 que é uma vpn, mas este não é o problema, pois testei também sem esta vpn e não funciona do mesmo jeito)... =============================== os dois cenários que tentei foram os seguintes: -------------cenário 1----------------- <ISP> ---- <RADIO> --- <UM_UNICO_CABO_DE_REDE> --- <SWITCH> --- <CABO_DE_REDE> --- <NIC1_MEU_FIREWALL_BSD> ......................................................................................................................|_______________<NIC2_MEU_FIREWALL_BSD> - Ou seja, liguei no switch e do switch peguei dois cabos para duas placas diferentes do MESMO computador - /etc/ppp/ppp.conf: default: set log Phase tun command marcelo1: set device PPPoE:vr3 set authname [EMAIL PROTECTED] set authkey 123mudar set dial set login add default HISADDR enable dns nat enable yes marcelo2: set device PPPoE:vr0 set authname [EMAIL PROTECTED] set authkey 321mudar set dial set login # add default HISADDR # enable dns # nat enable yes -------------cenário 2----------------- <ISP> ---- <RADIO> --- <UM_UNICO_CABO_DE_REDE> --- <NIC1_MEU_FIREWALL_BSD> - Ou seja, liguei o rádio diretamente em uma placa do computador - /etc/ppp/ppp.conf: default: set log Phase tun command marcelo1: set device PPPoE:vr0 set authname [EMAIL PROTECTED] set authkey 123mudar set dial set login add default HISADDR enable dns nat enable yes marcelo2: set device PPPoE:vr0 set authname [EMAIL PROTECTED] set authkey 321mudar set dial set login # add default HISADDR # enable dns # nat enable yes =============================== Nos dois casos o /var/log/ppp.log apresenta essas mensagens: Apr 26 10:40:39 mt ppp[1455]: Phase: Using interface: tun1 Apr 26 10:40:39 mt ppp[1455]: Phase: deflink: Created in closed state Apr 26 10:40:39 mt ppp[1455]: tun1: Command: marcelo1: set device PPPoE:vr3 Apr 26 10:40:39 mt ppp[1455]: tun1: Command: marcelo1: set authname [EMAIL PROTECTED] Apr 26 10:40:39 mt ppp[1455]: tun1: Command: marcelo1: set authkey ******** Apr 26 10:40:39 mt ppp[1455]: tun1: Command: marcelo1: set dial Apr 26 10:40:39 mt ppp[1455]: tun1: Command: marcelo1: set login Apr 26 10:40:39 mt ppp[1456]: tun1: Phase: PPP Started (ddial mode).
