    Default pptp server does not accept dlink router client

    Hallo,
    I have configured pptp server and I can connect windows client but when i connect dlink router client then connection is not established. May be some networking guru can guide me in right direction.

    /etc/ppp/options.ppp0
    Code:
    name pptpd
    debug
    noauth
    refuse-pap
    refuse-chap
    refuse-mschap
    require-mschap-v2
    require-mppe
    #require-mppe-128
    proxyarp
    nodefaultroute
    lock
    nobsdcomp
    nodeflate
    noipx
    mtu 1490
    mru 1490
    logfile /var/log/pptpd
    ~
    error log
