    thx for your answer, now seems that PPPoE negociation works better.
    but i still have no connection, and when I try with #ppp, I stay in ppp mode
    (ie I can't see the Ppp, PPp, PPP...) :

    ifconfig shows interfaces up & active.

    my ppp.conf is as follow :

    default:
    set log all
    set ifaddr X.X.X.X/0 10.0.0.2/0 <http://10.0.0.2/0>

    my_isp :
    set pppoe 3com
    set device PPPoE:xl0
    set mtu max 1492
    set mru max 1492
    set authname MY_USER
    set authkey MY_PWD
    disable ipv6cp
    set dial
    #set login
    add default HISADDR

    Seems that Chap/Pap authentification does not start... any help welcome,

    Rgds,
    Eric,
