Configuring NAT Port Forwarding for iSCSI Fault Domains

Port forwarding allows iSCSI initiators (servers or remote Storage Centers) located on a public network or different private network to communicate with Storage Center iSCSI ports on a private network behind a router that performs Network Address Translation (NAT).

For each Storage Center iSCSI control port and physical port, the router performing NAT must be configured to forward connections destined for a unique public IP address and TCP port pair to the private IP address and TCP port for the iSCSI port. These port forwarding rules must also be configured in parallel on the Storage Center fault domains to make sure that iSCSI target control port redirection functions correctly. Fault domains can only be modified by administrators.
