I have few ZCM agents behind the firewall. In official documentation are these ports required to be open on server side: 67, 69, 80, 443, 1433, 2638, 3306,
4011, 5550, 5950, and 7628 but there are no info what ports must be open in other direction. With these ports open on server side, my zcm server can't reach clients. What ports do I need to open in direction ZCM server -> Firewall -> ZCM agent?

Thanks in advance!
