5. Connection Configuration
NAS Connection
Caution
During the configuration phase
• For the NAS system of the ETERNUS DX, the following are used as IP addresses.
- 169.254.251.0/16
- 169.254.251.1/16
- 169.254.252.0/16
- 169.254.252.1/16
- 169.254.253.0/16
- 169.254.253.1/16
- 169.254.254.0/16
- 169.254.254.1/16
Therefore, connections with servers and clients with equivalent IP addresses are not possible.
• When the NFSv3 protocol or the NFSv4 protocol is used in a firewall environment, set the firewall so that
communication is possible between the NAS interface and the NFS client.
For communication from the NFS client to the NAS interface, enable ports 2049 / 111 / 28900 / 28901 /
28902 / 28903 (TCP/UDP).
For communication from the NAS interface to the NFS client, using ports 2049 / 111 (TCP/UDP) or the
port mapper to enable communication for the port and protocol that are assigned dynamically to the
NFS related daemon is required.
The ports/protocols that are assigned to the NFS related daemon depend on the settings of the NFS
client. Check the settings of the NFS client.
