Required Service Ports

To provide security on a network, you can deploy firewalls within your network architecture. Port numbers are used for creating firewall rules and to uniquely identify a transaction over a network by specifying the host and the service.

The following list shows the minimum ports required for creating firewall rules that allow full functionality of Oracle ZFS Storage Appliance:

Inbound Ports

  • icmp/0-65535 (PING)

  • tcp/1920 (EM)

  • tcp/215 (BUI)

  • tcp/22 (SSH)

  • udp/161 (SNMP)

Outbound Ports

  • tcp/80 (WEB)

  • tcp/443 (SSL WEB)

Note:

An outbound port of tcp/443 is used for sending Phone Home messages, uploading support bundles, and update notifications. For replication, use Generic Routing Encapsulation (GRE) tunnels when possible. This lets traffic run on the back end interfaces and avoid the firewall where traffic could be slowed. If GRE tunnels are not available on the NFS core, you must run replication over the front end interface. In this case, port 216 and port 217 must also be open.
