TIBCO EMS supports the Transmission Control Protocol (TCP) and Secure Socket Layer (SSL) protocols for network connections. Depending on how your network is configured, you need to configure your firewall to allow the data through this TCP or SSL connection.

If you are using SSL connections, you can use port 443 to make this connection. Port 443 is usually opened for SSL connections and is similar to port 80, which is generally opened for HTTP connections.

If you are not using SSL, you need to configure your firewall to allow the EMS client application to connect to the TCP port defined in the tibemsd.conf file.

Refer to your firewall documentation for specific information.
