Configuration Manager Remote Control Firewall

Dear Forum,

We recently bought Avast for Businiess. Now we got the Problem, that the Avast Firewall blocks Our Configuration Manager Remote Control tool to help our Clients in the field. When we toggle off the Firewall evrything works fine. We tried to open the following Ports which didnt work:
TCP: 2701, 2702, 135, 3389, 8530
UDP: 2701, 2702

Does anyone know which Port we have to Open?

Thank you very much.
Stefan
