comodo in lan

I have comodo on one comp in my LAN.
I have put my lan as trusted zone but when i try to connect
from another comp to the computer with comodo it wont let me in,
as soon as i shut comodo i can connect.
Connection FROM the comodo comp works but not TO it.
What might be wrong?

Have you checked the CFP logs (Activity → Logs) to see what there might be? It sounds like there is an inbound traffic blocking rule.
