What must be configured on the gateway Firebox for remote devices to send log messages to Dimension?

For remote devices to successfully send log messages to Dimension, it's essential to configure a policy that allows traffic to transmit these logs over the designated port, which is port 4115. This specific port is utilized for communication between the Firebox and Dimension, enabling the transfer of log data. By ensuring that a policy permits this traffic, you create a pathway for the remote devices to communicate with Dimension effectively.

The concept of allowing internal devices or establishing a connection in Dimension does not directly facilitate the actual transmission of log messages. While connectivity is important, it is the policy allowing traffic over the specified port that ultimately enables log data to flow. Additionally, the statement that log messages cannot be sent from remote devices is incorrect, as they can be sent provided that proper configurations are in place. Thus, configuring the appropriate policy is a critical step in ensuring log messages are received by Dimension.
