    Default Question regarding "Workaround to Sudden Loss of Internet Access Problem"

    I added a simple "custom" rule to ZAP's Internet Zone, allowing outgoing TCP on the ports neccesary for HTTP, FTP, POP, etc.

    ZAP has thus far worked fine, recent Windows Updates notwithstanding.

    In light of this (seemingly) simple solution, I find ZA's recommended workarounds a bit surprising...


    >> Option 1: Move Internet Zone slider to Medium

    That somewhat defeats the purpose of having ZA in the first place, doesn't it?

    Doesn't it make more sense to keep ZA at "High" and just add the simple custom rule?


    >> Option 2: Uninstall the hotfix

    From what I understand, the Windows Update addresses some fairly serious security issues, thus it would seem that uninstalling it as a bad idea.

    Again, doesn't it make more sense to keep Windows as patched up as possible, and just add the simple custom rule?


    >> 3 (advanced technical skills required): Add your DNS servers to trusted zone


    Are there advantages/disadvantages (in either the long term or the short term,) to doing it this way, as opposed to way that I did it?

    Thanks for all insights!!

    I've read the latest posts that you refer to Alanb, about allowing ports for various disciplines such as Outlook 2003 / IE7 / FF2 / etc.
    A d*mn fine question you ask - I'd like to hear from an EXPERT as to whether this is a flawed or recommended course of action...because with the little knowledge that I have, I'm incredibly nervous about it.
    Am I right in thinking that once
    a port is allowed (open), that any protection the FireWall offers is somewhat negated...?
    I'm quite prepared to be shot-down-in-flames...

    i did this or something similar by allowing outbound tcp connections on 80, 443, 110 and a couple of others that showed up in the firewall logs as i was running programs and they were failing.
    i felt reasonably safe doing so because i run behind a router which also functions as a stateful inspection firewall.
    my reasoning was that before the microsoft patch, when i open up a web page i am opening an outbound connection on port 80 (http) or 443 (https) or 110 (pop).
    it would be interesting for someone who understands the details to explain exactly what is broken in zonealarm by something microsoft did.

    At a minimum, ZA needs to email (text only as port 80 to get html is blocked)
    all customers and tell then the correct procedure that is
    super simple
    for those frustrated and
    not technical savvy
    to perform ASAP... like hours ago.

    I tried option 3 of the fix for Internet access after Tuesday's update ... it doesn't work! I already have my DNS Servers in the trusted Zone.
    I had to allow outbound TCP ports 25, 80, 443, and 465 to make it work!!
    Chat is back logged, so is customer service, premium support.

    When I ran into problem accessing internet in the afternoon, after the familiar MS update patches, I tried adding DNS servers to trusted zone. I'm not technically oriented. But I doubted whether it would work. Sure it did not. I then found a similar suggestion from ZA. It is pretty surprising they posted this option 3.

    I am not happy sliding the security level to medium. I have also kept the security at the highest but allowed outbound TCP ports 25, 80, 443, and 465. It did the job but what are my downside? Can some one advise please?

    I'm not sure switching Windows Firewall makes sense.

    Thanks
