External communications

PDFs
Clients need to communicate with grid nodes to ingest and retrieve content. The ports used depends on the object storage protocols chosen. These ports need to be accessible to the client.
Restricted access to ports
If enterprise networking policies restrict access to any of the ports, you can use load balancer endpoints to allow access on user-defined ports. You can then use untrusted Client Networks to allow access only on load balancer endpoint ports.
Port remapping
To use systems and protocols such as SMTP, DNS, SSH, or DHCP, you must remap ports when deploying nodes. However, you should not remap load balancer endpoints. For information about port remapping, see the installation instructions:
Ports used for external communications
The following table shows the ports used for traffic into the nodes.
