What To Do
The Sophos Agent service binds to an ephemeral port, selected from the Operating systems' list of available ports. This randomly selected port is only used for communication with the Sophos Message Router service running on the same system.
No extra firewall configuration is required, as the Agent service does not directly communicate with other systems.
If binding to an ephemeral port is causing a conflict with a 3rd-party application, the range of ephemeral ports can be modified. Please see the instructions for Windows and Linux platforms, or refer to your operating system documentation.
