  1. pptp vpn server cofiguration problem?

    Hi all,
    I am trying to setup pptp vpn server in office to connect windows
    clients from home, but no success for last two weeks. my linx system
    has
    1. SuSe Linux 8.2 (kernel 2.4.20-4GB)
    2. pptpd --version (PoPToP v1.1.2)
    3. two ethernet cards
    eth0:142.120.20.222 local connection
    eth1:162.159.237.251 internet connection(permannetly connected with
    fixed ip)
    4. configured Windows XP PPTP client as documented,all
    authentication(PAP,CHAP,MSCHAP) enabled,ISDN modem connection for
    internet access

    when i connect windows xp client, it stays in authentication mode
    until it is disconnected. on linux side following are my configuration
    files & log messages

    ----------pptpd.conf------------------------------------
    speed 115200
    option /etc/ppp/options.pptpd
    debug
    localip 142.120.20.222
    remoteip 142.120.20.5-9
    pidfile /var/run/pptpd.pid
    ---------end pptpd.conf--------------------------------
    in log file,local ip is different,don't know it should be eth0 or eth1
    ip?

    ---------/etc/ppp/options.pptpd----------------
    ## CHANGE TO SUIT YOUR SYSTEM
    lock

    ## turn pppd syslog debugging on
    debug

    ## change 'pptpd' to whatever you specify as your server name in
    chap-secrets
    name damokles

    mtu 1490
    mru 1490

    # This option applies if you use ppp with chapms-strip-domain patch

    #+chapms-v2

    # These options will tell ppp to pass on these to your clients
    # To use ms-wins or ms-dns in options.pptpd it must exist in
    /etc/resolv.conf
    #ms-wins your.server.here

    ---------------------chap-secrets----------------------------------
    # Secrets for authentication using CHAP
    # client server secret IP addresses

    ----------------------end chap-secrets----------------------------

    when client is connected I can't see any ppp0 inerface which should
    be?..
