Comodo blocks other non-comodo fw computers

I am trying to test out this firewall on my network. It works great. I like the fact that it gives me a great degree of control.

The thing is, my comodo firewall client was affecting other clients on the network. Soon after I had installed comodo, I noticed that another computer on the network had a reduced number of computers it could see.

I also recently allowed an automatic update for comodo, and the entire network had zero-internet access via internet explorer. And programs accessing shared resources were halted. No one was able to access the internet.

Is there any way to configure the firewall so that it does not affect other computers on the network?

I’m not too sure why this is happening. Could someone please help.

Hi lasnoci, Read m0ng0d’s post on Network Control Rules I am sure it covers what you are looking for.
