    Default VPC/Win2000Pro through OS X ipfw firewall: Safe?

    Greetings

    I have VirtualPC 5.something-or-other with Windows 2000 Pro installed on
    my 2002 G4 Quicksilver 933, OS X 10.2.6. I haven't used VPC in a while,
    and I never have done any of the "Windows update" stuff on it. It runs
    with "shared networking" so the VPC can share the net connection with
    the Mac. Works great.

    Now I want to use it again, but with all this msblaster/nachi stuff
    that's been going around, I don't want my VPC to get infected ;)

    I'm on a cable modem, and I have the OS X 10.2 built-in ipfw firewall
    enabled with no ports open.

    I've read that msblast/nachi attacks Windows RPC on port 135 (right?),
    but that port, along with all others, is closed by ipfw.

    So I ask: given my setup will my VPC be safe from msblast/nachi attacks?
    In other words, the ipfw blocks attacks on port 135 (or whatever) before
    the attack can make it to the VPC. Is this right?

    BTW, I don't run LookOut! Distress!^W^WOutlook Express or any other
    mailer on the VPC, so M$-targetted email viruses/worms are not a concern
    for me.

    Thanks in advance for all help.

    My boss just tested this. Apparently, if you tell VPC to use your
    Mac's network settings, you can't get infected. But if you tell VPC
    to set up the network connections then make sure you are patched up!

    Thanks much for the feedback. That's pretty much what I figured.
    The VPC has its networking set up to use what it calls "Shared
    networking with sockets". And, yep, it appears that ipfw
    protects the VPC. In fact, I went to a few of the security scan
    web sites out there (using Mozilla Firebird on the VPC) and they
    said that the VPC is locked down tight.

    I also got all of the Microsoft "critical" updates for Win2000,
    and after a couple of hours of downloading, installing, and
    rebooting the VPC, I think my Win2000 is up-to-date and safe ;)

    Thanks again for your help.
