    Padrão VPN ( avanbçado)

    Prezados,


    busco ajuda, pois realmente estou desesperado.

    Posasuo um fedora core 5, com openswan isntalado, fechando vpn com um cisco PIX.

    O tunel fecha, porem não consigo dar nem receber os replys dos ping spor exemplo..

    Meu log fica assim:


    Código :

    Muito estranho, meus arquivos de configuração estão assim:
    Código :
    #ipsec auto --up pix route add -net 200.184.147.0 netmask 255.255.255.0 dev ipsec0
     
    # /etc/ipsec.conf - OpenSWAN IPSec configuration file
     
    #The version information is needed for OpenSWAN
     
    version 2.0
     
    # basic configuration
    config setup
         interfaces="ipsec0=eth0"
         klipsdebug=none
         plutodebug=none
     
     
     
     
    # Add connections here
     
     
     
    conn acotel-m4u
        type= tunnel
        right=x.x.x.x
        rightnexthop=x.x.x.xGW
        left=y.y.y.y
        leftsubnet=y.y.y.y/32
        leftnexthop=y.y.y.yGW
        esp=3des-md5-96
        pfs=yes
        disablearrivalcheck=yes
        authby= secret
        keyexchange=ike
        auto=start
    # Disable Opportunistic Encryption
     
    # essential for inertoperating with Cisco devices
    conn block
         auto=ignore
     
    conn private
        auto=ignore
     
    conn private-or-clear
        auto=ignore
     
     
    conn clear-or-private
        auto=ignore
     
     
     
    conn clear
        auto=ignore
     
    # End of config for disabling Opportunistic Encryption
    "/etc/ipsec.conf" 57L, 979C

    e meu ipsec.secrests está:

    x.x.x.x y.y.y.y : PSK "key"


    Por favor, estou desesperado.. alguem que ja teve essa experiencia poderia me ajduar?

    serei muito grato.

    que eu saiba, vc não consegue nunca resposta de um gateway VPN. Vc pode pingar os hosts que estão ATRÁS dos gateway, mas não êles mesmos.

    Experimente pingar um host qualquer da LAN do "outro lado", a partir de um host qualquer "dêste lado".
