Port
Service
Protocol
Access Direction
Description
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.
514
Remote Logging
UDP
Outbound
Allows the appliance to send log
messages to remote syslog servers. If
closed, log messages cannot be sent to
remote syslog servers.
636
LDAPS
TCP/UDP
Outbound
Secure LDAP queries. If closed, secure
LDAP authentication will be unavailable.
1234
NFS mountd
TCP/UDP
Bi-directional
Used for the mount service, which is
a core component of the NFS service
(versions 2, 3, and 4).
1468
Remote Logging
TCP
Outbound
Allows the appliance to send log
messages to remote syslog servers. If
closed, log messages cannot be sent to
remote syslog servers.
2000
SSHD
TCP
Inbound
SSHD for serviceability (optional)
2049
NFS I/O
TCP/UDP
Bi-directional
Used to provide NFS services.
3268
LDAP
UDP
Outbound
Unsecure LDAP queries. If closed,
Unsecure LDAP authentication queries will
be unavailable.
3269
LDAPS
UDP
Outbound
Secure LDAP queries. If closed, Secure
LDAP authentication queries will be
unavailable.
4000
STATD for NFSv3
TCP/UDP
Bi-directional
Used to provide NFS statd services. statd
is the NFS file-locking status monitor
and works in conjunction with lockd to
provide crash and recovery functions for
NFS. If closed, NAS statd services will be
unavailable.
4001
NLMD for NFSv3
TCP/UDP
Bi-directional
Used to provide NFS lockd services.
lockd is the NFS file-locking daemon. It
processes lock requests from NFS clients
and works in conjunction with the statd
daemon. If closed, NAS lockd services will
be unavailable.
4002
RQUOTAD for
NFSv3
TCP/UDP; UDP
Inbound; Outbound
Used to provide NFS rquotad services.
The rquotad daemon provides quota
information to NFS clients that have
mounted a file system. If closed, NAS
rquotad services will be unavailable.
4003
XATTRPD
(extended file
attribute)
TCP/UDP
Inbound
Required for managing file attributes in a
multi-protocol environment.
4658
PAX (NAS server
archive)
TCP
Inbound
PAX is an appliance archive protocol that
works with standard UNIX tape formats.
8888
RCPD (replication
data path)
TCP
Inbound
Used by the replicator (on the secondary
side). It is left open by the replicator as
soon as some data has to be replicated.
