Clients need to communicate with grid nodes and, by extension, the servers that host them in order to ingest and retrieve content. The ports used depends on the protocols chosen to ingest and retrieve content.
If enterprise networking policies restrict the availability of any of the ports used for traffic into or out of the nodes, you can remap ports when deploying nodes.
The following table shows the ports used for traffic into the nodes.
| Port | Protocol | Allows access to |
|---|---|---|
| 22 (TCP) | SSH | Servers being used for software installation and maintenance |
| 80 (TCP) | HTTP | Admin Nodes (redirects to 443) |
| 161 (TCP/UDP) | SNMP | Admin Nodes |
| 443 (TCP) | HTTPS | Admin Nodes |
| 445 (TCP) | SMB | Audit logs on Admin Nodes |
| 905 (TCP) | NFS statd | Audit logs on Admin Nodes |
| 2049 (TCP) | NFS | Audit logs on Admin Nodes |
| 8022 (TCP) | SSH | Servers being used for software installation and maintenance |
| 8082 (TCP) | S3 | API Gateway Nodes |
| 8083 (TCP) | Swift | API Gateway Nodes |
| 9022 (TCP) | SSH | StorageGRID Webscale appliances |
| 18082 (TCP) | S3 | Storage Nodes |
| 18083 (TCP) | Swift | Storage Nodes |
The following table shows the ports used for traffic out of the nodes.
| Port | Protocol | Used for |
|---|---|---|
| 25 (TCP) | SMTP | Alerts and AutoSupport. |
| Configurable (TCP) | SMTP | Alerts and AutoSupport. You can override the default port setting of 25 using the Email Servers page. |
| 53 (TCP/UDP) | DNS | Domain name system |
| 123 (UDP) | NTP | Network time protocol service |
| 389 (TCP/UDP) | LDAP | Accessing the LDAP server from Storage Nodes that run the ADC service |
| 80 (TCP) | HTTP | (Default) Platform services messages sent to Amazon Web Services (AWS) or another external service from Storage Nodes that run the ADC service |
| 443 (TCP) | HTTPS |
|
| Configurable (TCP) | HTTP | Platform services messages sent from Storage Nodes that run the ADC service Tenants can override the default HTTP port setting of 80 when creating an endpoint. |
| Configurable (TCP) 8082 for destination API Gateway Nodes |
HTTPS | Platform services messages sent from Storage Nodes that run the ADC service Tenants can override the default HTTPS port setting of 443 when creating an endpoint. Port 8082 is used by default when StorageGRID Webscale is used as a destination endpoint for CloudMirror replication |
