Greetings --
WinXP's ICF recognizes Microsoft's Windows Messenger IM
application as a valid, authorized application, so it isn't blocked,
no more than is Internet Explorer or Outlook Express. In fact,
WinXP's ICF doesn't block _any_ outgoing traffic. It's simply not
intended or designed to do so.
WinXP's built-in firewall is _adequate_ at stopping incoming
attacks, and hiding your ports from probes. It doesn't give you any
alarms to tell you that it is working, though. Nor is it very easily
configurable. What WinXP also does not do, is protect you from any
Trojans or spyware that you (or someone else using your computer)
might download and install inadvertently. It doesn't monitor
out-going traffic at all, other than to check for IP-spoofing, much
less block (or at even ask you about) the bad or the questionable
out-going signals. It assumes that any application you have on your
hard drive is there because you want it there, and therefore has your
"permission" to access the Internet. Further, because the ICF is a
"stateful" firewall, it will also assume that any incoming traffic
that's a direct response to a Trojan's or spyware's out-going signal
is also authorized.
ZoneAlarm, Kerio, or Sygate are all much better than WinXP's
built-in firewall, and are much more easily configured, and there are
free versions of each readily available. Even Symantec's Norton
Personal Firewall is superior by far, although it does take a heavier
toll of system performance then do ZoneAlarm or Sygate.
If you're using AOL, you'll either need to find a 3rd party
firewall that is compatible with AOL, or switch to a real ISP that is
compatible with the real Internet. This is because AOL is an on-line
content provider that ignores international Internetworking standards
in favor of its own proprietary products, and has deliberately made
its connection software incompatible with both WinXP's built-in
firewall and WinXP's Internet Connection Sharing feature. AOL's
proprietary connection applet is deliberately designed to preclude
your setting/adjusting any of its properties, to include
enabling/disabling WinXP's ICF and ICS.
I believe that the free version of ZoneAlarm (
www.zonelabs.com) is
AOL-compatible. Sygate's free Personal Firewall
(
http://smb.sygate.com/buy/download_buy.htm ) is also AOL-Compatible
