To-M,

I believe the commands you sent are to configure the Open-E NIC settings for the target box. I am specifically looking to configure iscsi target IP access. From the web GUI this can be achieved by Configuration->ISCSI Target Manager->Targets. Select a Target, then you can configure which IPs have access to that ISCSI Target.

Most other commands are available in the CLI such as
iscsi_target_create - to create a target
iscsi_target_assign - to assign to a volume

The only command I do not see is a way to set the iscsi target IP access control.
