# Configure your firewall to allow communications between the ESX/ESXi host and the workstation running vSphere Client using port 903. For more information, see Testing port connectivity with Telnet (1003487).
If port 903 is not open or cannot be opened in your environment, enable the vmauthd proxy. This forces remote console communication to be sent on port 902 on the Service Console, instead of 903.
Note: By enabling this setting there may be degradation in the performance under heavy usage while communicating to the ESX host service console.
