    My apologies if this is a FAQ - I have been RTFMing
    for two days now and haven't been able to find an
    answer.

    I have a machine running RH 9 with kernel 2.4.20-31.9
    and openssh 3.9p1/openssl 0.9.7e. sshd is on port 22,
    and there is a Linksys router forwarding port 22 to
    the RH box, which is on a home LAN.

    I have a laptop which can boot into either Windows XP
    or Debian. In both cases the network configuration is
    the same (static IP). When it boots into Debian, it
    can ssh to the router's external address and connect
    to the RH machine. However, when it boots into Windows
    XP, it can't connect with ssh (I tried Cygwin, Putty,
    and WinSCP) via the router's address; in all cases the
    client times out. When I telnet to port 22 on the
    router, I get nothing until I type some random
    characters and hit enter a couple of times, at which
    point I get the SSH version number.

    Connecting using the RH machine's LAN address works
    fine in all cases.

    Connecting from a remote Linux machine which is not on
    the local LAN, I can SSH in properly, and telnetting
    to port 22 immediately shows the version number.
    Connecting from a remote Windows machine which is not
    on the local LAN shows the exact same behavior as when
    I connect from a local Windows machine, i.e. it
    doesn't work.

    In summary: ssh/telnet/putty/winscp from Windows to
    the router always times out, ssh/telnet from Linux to
    the router always succeeds. So it appears to be a
    Windows/Linux problem rather than a local/remote
    problem.

    Here's the funny part: this problem first appeared
    when I installed a new a 3c2000 gigabit ethernet card.
    Using my old 10 megabit 3c900 card makes this whole
    problem go away.

    Thanks in advance.
    James
