iSCSI and Mac, no connection


I have the network solutions/Global SAN iSCSI connector and I cannot create a connection on my Mac. I know the iSCSI iniator works as I can create connections to my QNAP NAS. Is there some trick regarding iSCSI1/2 on the back, or the “Active Interface” in the console that I should be aware of? The manual really is crap.
