c. In the Remote iSCSI Controller Ports table, select one or more iSCSI ports on the remote Storage Center orPS Group to
use for the iSCSI connection.
6. If network address translation (NAT) is performed for the connection between the Storage Centers, congure NAT settings.
NOTE: NAT port forwarding is supported only if both Storage Centers are congured for legacy port mode, or if both
Storage Centers are running version 6.5 or later and congured for virtual port mode. PS Groups do not support
NAT port forwarding.
a. The Congure NAT dialog box opens.
b. Congure port forwarding information for each local and remote iSCSI port.
• In virtual port mode, the NAT IP Address and NAT Public Port elds display the translated public IP address and port.
Click Change to modify these elds.

Bidirectional CHAP checkbox to enable the Storage Centers to challenge the fault domains on each Storage Center for a
shared secret.
9. If replicating to a PS Group, congure the storage pool for the destination volume.
a. From the Storage Pool drop-down menu, select the storage pool that the destination volume will use.
b. In the Delegated Space (For Remote PS Group) eld, set the amount of space allowed for the destination volume.
