Table 11. Appliance network ports (continued) Port Service Protocol 500 IPsec (IKEv2) UDP 514 1468 3033 3260 Remote Logging UDP Remote Logging TCP Import iSCSI TCP/UDP TCP 3261 4420 Data mobility TCP I/O Controller TCP Access Direction Description Bi-directional To make IPSec work through your firewalls, open UDP port 500 and permit IP protocol numbers 50 and 51 on both inbound and outbound firewall filters. UDP Port 500 should be opened to allow Internet Security Association and Key Management Protocol (ISAKMP) traffic to be forwarded through your firewalls. IP protocol ID 50 should be set to allow IPSec Encapsulating Security Protocol (ESP) traffic to be forwarded. IP protocol ID 51 should be set to allow Authentication Header (AH) traffic to be forwarded. If closed, IPsec connection between PowerStore appliances will be unavailable. Outbound Allows the appliance to send log messages to remote syslog servers. If closed, log messages cannot be sent to remote syslog servers. Outbound Allows the appliance to send log messages to remote syslog servers. If closed, log messages cannot be sent to remote syslog servers. Outbound Required for storage import from legacy EqualLogic Peer Storage and Compellent Storage Center systems. ● Inbound for Required to provide the following access Host and ESXi to iSCSI services: host access ● External host iSCSI access ● Bi-directional for ● External or PowerStore embedded replication ESXi host iSCSI access ● Outbound for storage import ● Inter cluster access for replication ● Storage import access from legacy EqualLogic Peer Storage, Compellent Storage Center, Unity, and VNX2 systems If closed, iSCSI services will be unavailable. Used by Data mobility to support reasonable replication performance on low latency connection. Bi-directional Used by Data mobility to support reasonable replication performance on high latency connection. ● Inbound for Required to provide the following access Host and ESXi to NVMe/TCP I/O Controller services: host access ● External host NVMe/TCP access ● Bi-directional for ● External or PowerStore embedded replication ESXi host NVMe/TCP acces ● Outbound for storage import ● Inter cluster access for replication ● Storage import access from legacy EqualLogic Peer Storage, Compellent Storage Center, Unity, and VNX2 systems If closed, NVMe TCP I/O I/O Controller services will be unavailable. 26 Port usage
