    I thought I would see how much protection each of my firewalls has been providing, so I ran GRC.com's Shields Up! Here's a brief summary of what I did.

    1) I shut down ZoneAlarm on my computer(s).

    Ran the test and everything reported as STELTH, except port 21 as CLOSED.
    I disabled my UPnP setting for port 21 (via Windows xp) and retested - port 21 reported as STEALTH.

    2) I disabled my WRT54G firewall (ZA already shut down).

    Couldn't even get to Shields Up! page - getting time out error.
    Enabled the firewall - no problem whatsoever.

    ~~~

    My questions are as follows:
    A. Is the behaviour with my port 21 and UPnP normal?
    (UPnP is enabled in the router)
    B. Why was I getting time out error with Shields Up! when I disabled my WRT54G firewall?
    (no problem going to other sites)

    Thanks.
