Internal grid node communications

The following ports must be accessible to grid nodes on the Grid Network. Ensure that the required ports for the grid node type are open on the server.

Configuration of the following ports is only required if you need to define firewall restrictions that are external to VMware networking.

If enterprise networking policies restrict the availability of any of these ports, you can remap ports when you deploy nodes using the VMware Vsphere Web Client, or by using a configuration file setting when automating grid node deployment.
