Sharing Broadband with Zonealarm

  Joe R 12:05 19 Feb 2006

Hi all,
I have just connected my own system, to my Kids System using a cat crossover cable, and set up a network, so that they are able to share my broadband connection.

Everything went well, except for the fact that, I have to turn my Zonealarm firewall off on my own P.C., so that the kids can access the net. I've added their system to the trusted zone in the firewall, but still cannot get access for the other machine unless, I turn the firewall off.

Can anyone tell me how to share access, with my firewall turned off.?

P.s. Both pc's are protected by Avast as well as Zonealarm.

That should read, Can anyone tell me how to share access, with my firewall turned on.?

Has caused be probs in the past. The one fix that worked for me was reinstalling it with all computers on the network. The other thing that might work is changing the zone of the other machine from trusted to internet.

the other machine was originally on "inernet" but with the same problems.

I'll try reinstalling, but if this does not work, i'll just run my own without a firewall.

In Zone Alarm in the "host" PC, you need to reduce the "Internet Zone Security" level from High to Medium or "Internet Connection Sharing" traffic will be blocked.

I've already tried this with zonealarm, and even had it at the "lowest" setting, but with no success.

OK, also in Zone alarm, in the Trusted Zone of both PCs, click "Add" and select "Subnet". Enter:

IP address -

Subnet Mask -

Description - {anything} but it needs an entry. Click "OK" and then in the main window "Apply".

Thanks, tried this solution, but still no joy.

And if that doesn't work, just use the Windows XP one that comes with the OS. As long as your virus checker and spyware scans are working, that will give you some protection.

Not having a firewall at all, especially with broadband, is rather unwise.

Unlikely but worth checking,ZA/program control/generic host. Make sure generic host is not blocked.

Thanks for the input, but everything is ok there. I'll have another go later on, and see what else I can come up with.
