Note: The NFS v2/v3 protocol family supports dynamic ports via the portmap protocol. Our implementation of it uses static ports, configurable with rpcport , defaulting to the numbers below for lockd, mountd, NFS, rquota and statd.
* On an HNAS server, the management IP address refers to the admin service node and cluster node IP addresses. On a NAS module, it refers to the NAS module management IP address.
NAS as a client
The NAS server uses these destination ports on a peer server.
| Port | Protocol | |
| 25 | SMTP | TCP |
| 53 | DNS | TCP/UDP |
| 80,443 | Data Migrator to Cloud | TCP |
| 88 | Kerberos | TCP/UDP |
| 123 | NTP | UDP |
| 139 | SMB (CIFS) over NetBIOS | TCP |
| 162 | SNMP traps | UDP |
| 389 | LDAP | TCP/UDP |
| 445 | SMB over TCP | TCP |
| 464 | Kerberos Password Change (kpasswd) | TCP/UDP |
| 636 | LDAP over TLS | TCP/UDP |
| 1344 | ICAP AV | TCP |
| 2049 | NFS | TCP/UDP |
| 4048 | mountd | TCP/UDP |
| 59550 | Object replication | TCP |
| Set by the peer server | NDMP data port | TCP |
External SMU (listening ports)
| Port | Protocol | IP address type | |
| 22 | SSH | TCP | Management * |
| 25 | SMTP relay (Only in SMU gateway mode) | TCP | Management * |
| 80 | HTTP GUI | TCP | Management * |

| 162 | SNMP trap receiver | UDP | Management * |
| 443 | HTTPS GUI | TCP | Management * |
| 59515-59536 | Quorum device (HNAS server only) | UDP | Cluster node |
* On an HNAS server, the management IP address refers to the admin service node and cluster node IP addresses. On a NAS module, it refers to the NAS module management IP address.
External SMU as a client
The external SMU uses these destination ports on a peer server.
| Port | Protocol | |
| 25 | SMTP relay | TCP |
| 123 | NTP | UDP |
| 443 | HTTPS Standby SMU Backups | TCP |
| 8443 | SOAP requests to NAS | TCP |
