blocking a trusted system

I have comodo cis on system “A”. I want system “B” to have a complete pass as far as system “A”'s firewall is concerned. I thought I configured the firewall that way in the two policy sections and the network section yet comodo cis still drops traffic from system “B” logging it at an intrusion attempt. (oh no searching for a printer lets flag it as an intrusion!)

How do I let system “B” do whatever it wants to system “A” and not have cis complain about it?
