    I think you're right, it's not a kernel issue. You should run "tcpdump -qni
    ppp0" in a xterm before you start netscape.

    You will probably see dns requests going out. You should check to make sure
    that you are not blocking incomming udp ports (1024-5000 for bind, not sure
    about resolver...) as that would lengthen the response time considerably if
    only a few are open, and completely stop you if all are blocked.
