Client is not Connecting to the BigFix Server or Relays

By default, server-agent and CPM server-client communication occur using port 52311. This port is automatically allowed by the Trend Micro Common Firewall.

If you have installed BigFix using a different port, the firewall will automatically recognize that port. However, if you have re-installed the server and in that installation designated a different port, the firewall will not pick up that change. Add an exception in your firewall policies.
