Comodo's Firewall in a Home Network

Hi there,

I recently installed Comodo’s Firewall ( I really liked the interface and the product itself) in one of my home network PC’s. Everything went ok, I disabled the Comodo Firewall from running at the startup to prevent it from messing up my network avoiding to access the other computers.
Yesterday I noticed that I could not access my network, even shutting down CF I didn’t have access to my network. I checked and my netwok was in the trusted zone and the IP range was correct. I uninstalled CF from that PC and gained access again to my network!
Does anyone knows how can I have CF installed without messing up my network?

Thanks in advance,
Bruno
