View Full Version : Internet connection sharing and firewalls

02-06-2004, 01:03 PM
Hi all.

I have a wireless network at home - one desktop win XP home that connects to the net, one win xp laptop and another desktop, this time running win 2000 professional.

I have ICS running so the laptop and the win 2000 machine can access the net - this works sweetly as long as i disable the Zone Alarm firewall.

If the firewall is running, I cannot browse the web on the 'clients'

I have added a trusted IP range of -

AND have added individual trusted IP addresses that the two clients run.

The firewall blocks net access anyway.

- - I disabled the firewall for one day and night, and ended up with the Sasser worm. (which I have since fixed)

Any Ideas?

Hi Jaxson, what version of Zone Alarm are you running? If it is the free version then you will find that ICS does not work. It is a "feature" of the Pro version.
You could try using Sygate version 5 or later which has full ics support and is free for personal use.
Have a look here. http://smb.sygate.com/products/spf_standard.htm
Hope this helps

First of all, to prevent the Sasser worm you need to be going to Windows Update. This is a MUST!

Second of all, check here for a quick prevention of the worm while you're getting the Windows Updates:

(Is it just me or are Viruses really stupid nowadays!)

Next, try making your Network Card a trusted device.

Ive not done ICS with Zone Alarm, but get your Updates and prevent the worm using the technique from the above URL.

I see now on Zone Alarm's website they tell you to upgrade to pro if you want to use ICS. :o(

I always liked ZA.
I might even pay for it. I've been using it for three years or something for free.

Thanks CS - I used 'Stinger' to get rid of the Sasser Worm.

I had always allowed the automatic updates to install whenever the system saw fit, but there may have been something wrong with it.

You could use Xp's firewall?
It actually works pretty good.
