Multi-factor authentication requires the following ports to be open for inbound communication and domain traffic:
- Port 8080 for HTTP API proxy
- Port 8443 for secure HTTP (HTTPS) connections
Installing the connector automatically sets Windows firewall rules to open these ports. However, if you are using a third-party firewall instead of the default Windows firewall, you should manually modify the port rules to allow the Centrify Agent for Windows to communicate with the Centrify Connector. Both ports are required because integrated Windows authentication over HTTPS uses port 8443 to enable the connector to receive inbound connections from the agents.
