Each NAS server interface can be configured on a specific VLAN. Interfaces that reside on different VLANs can be created, even if they are within the same NAS server. Each IP address must be unique, even if they reside on different VLANs. You cannot create a NAS server interface that resides on the same VLAN as the storage VLAN, which is used for iSCSI and replication connectivity.
