PPP routing failure - FreeBSD

Hi everyone - I'm experiencing some funky routing failures when I dialup netscape internet via user-level PPP: I can negotiate IPCP fine; get a point-to-point link via tun0: myaddr: 172.143.224.146; hisaddr: 63.152.0.70 When the default route is setup to 63.152.0.70, all of my packets are blackholed after the first router hop. I am not using NAT. The PPP link works perfectly fine in windows dialup networking. So I dunno what is wrong. When I look at the routing table in windows, it seems backwards: DEST NM GW IF default 0 myaddr ppp hisaddr 0xffffffff myaddr ppp localhost 0xff000000 localhost localhost ...

    Default PPP routing failure

    Hi everyone -
    I'm experiencing some funky routing failures when I dialup netscape internet
    via user-level PPP:
    I can negotiate IPCP fine; get a point-to-point link via tun0:
    myaddr: 172.143.224.146; hisaddr: 63.152.0.70
    When the default route is setup to 63.152.0.70, all of my packets are
    blackholed after the first router hop. I am not using NAT.
    The PPP link works perfectly fine in windows dialup networking. So I dunno
    what is wrong. When I look at the routing table in windows, it seems backwards:

    DEST NM GW IF
    default 0 myaddr ppp
    hisaddr 0xffffffff myaddr ppp
    localhost 0xff000000 localhost localhost
    myaddr 0xffffffff localhost localhost
    myaddr.255.255* 0xffffffff myaddr ppp
    multicast multicast myaddr ppp

    *this is the first 2 dotted quads of myaddr appended with 255.255

    If I try to manually set these routes in 5.3-R, I still can't get out :(
    Setting ADD DEFAULT MYADDR doesn't work, because ppp will still think MYADDR
    is 0.0.0.0. Either I need sleep or something is funky here...

    Check out the install guide at
    http://www.unixguide.net/freebsd/fbsd_installguide/index.php
    it has the best step by step instructions for using userppp.

    Yes it was a sleep issue (and not the sleep(2) kind haha). *facepalm*
    Apparently the POP uses a 2 stage authentication process. First, you use
    unix/slip style authentication after which the POP then initiates CHAP.
    I had specified the inccorect password for CHAP but after the initial
    autentication the POP still assigned me an IP; albeit one that didn't talk
    to anything but the next hop and its nameserver. it's all good now!
