I am already running Norton Internet Security. Is it
advantageous to run a second windows firewall or should I
just turn it off. Is it possible for one firewall to catch
somthing the other didn't?
Frank
 
There is little point in running two firewalls.. stick with the Norton
Firewall..
 
To avoid conflicts and error messages, it is recommended
that you only use one firewall. Attempting to use two firewalls
will not afford any additional protection.

Windows XP Internet Connection Firewall blocks incoming attacks only

If using a third-party firewall:

Open your Control Panel, then double-click the Security Center icon.
In the left side, click on the link titled: "Change the way Security Center
alerts me". Next, uncheck the Firewall Alert Setting, then click OK.

Hi Frank

If you are talking about the XP Firewall - it doesn't monitor outgoing
access to the Internet. Running two programs of the same type at the same
time 'could' cause conflicts. I have disabled the XP Firewall as I am
running a 3rd party '2-way' Firewall.
 
I seem to have XP's SP2's pretty firewall, and NIS's firewall and Zonalarm
Pro installed, ...it seems that Zonalarm is often configuring rules i.e. I
quite often get a Zonalarm prompt about something or other, ...so what's the
windows XP Home ed. one doing in there ? :-)

regards, Richard

You can leave it on if they do not conflict.

Yes, if they use different firewall technologies.
For example, I have run the following three firewalls at the same time:
Windows Firewall:
Provides bootup protection
Can block source address spoofing
ZA free:
Control of an application's use of TCP/IP
BID (BlackIce):
ID protection (monitors for suspicious activity)

No. Turn off the Windows firewall. You achieve no extra
protection, you incur the extra overhead of running two
firewalls, and you run the risk (probably small, but not zero) of
conflicts between them.
See
http://www.microsoft.com/athome/security/protect/firewall.mspx

which includes the following:

Q. Should I use both the built-in firewall and a software
firewall from a different company on my Windows XP computer?



A. No. Running multiple software firewalls is unnecessary for
typical home computers, home networking, and small-business
networking scenarios. Using two firewalls on the same connection
could cause issues with connectivity to the Internet or other
unexpected behavior. One firewall, whether it is the Windows XP
Internet Connection Firewall or a different software firewall,
can provide substantial protection for your computer.

Actually, I run two firewalls, Sygate and my Edimax router ;-)

Since I also have a router, in that sense, I do too. But Frank's
question, and my reply, dealt with software firewalls.

I was just being a wise ass. Sorry ...

....Attempting to use two firewalls

Not True. :) Without knowning the specs of each FW, this is only a RoT. Once
the specs are known, several FW's could be used to protect (and allow)
different activity, at differnt times and stages and states.

OK, I'm never talking about FW's again for the rest of my life. :)

Well, maybe one more time. :)

Update to the newest ZA PRO and it wil turn off the WFW, although that may
also act as the ICS depending on your network configuartion(but the FW part
will be off).

Dump NIS, it's a hog. (I think Norton got it's toys mixed up with something
important. Moreover, Norton is an ackqasition company, not a champion of
great works.)

AWWWWWW, at long last. A FW brother! ;)

I KNEW I WAS NOT ALONE on this forsaken plaent. LOL

Turns out I had to kill the Windows Firewall anyway...I
couldn't connect to the internet anymore...had to run the
network and connection wizards to reinstate it....Windows
still sucks as expected!

Your last comment is absolutely correct. I have been posting this for
sometime in this NG w/o causing the major respondents (incl MVPs) to
challenge their uneducated opinion via personal testing and study of
TCP/IP-firewalls. If a user understands TCP/IP and firewalling, he/she has
your opinion, otherwise he/she listens to Steve Gibson, MS, or MVPs in this
NG.

If the MVPs had to take a test on firewalls (and TCP/IP?), the results would
be interesting. Or predictable!

Yes...it can sometimes be a good idea to run more than one. See CZ's
post.

I also run more than one...plus my router NAT. Each one has a feature
that the other doesn't have...which I find very important.


Have a nice one...
