By default, the Dell License Server listens on TCP port 27000. When you change it to a non‑default port, you must choose from the range 27000–27009, keeping at least ports 27000 and 27001 open for proper operation.

The vProxy appliance supports three transport modes - HotAdd, NBD, and NBDSSL - but Dell EMC strongly recommends using HotAdd for the fastest, most efficient VM backups. HotAdd mounts target VM disks directly into the proxy VM’s address space, avoiding network hops, reducing latency, and offloading I/O from the ESXi management network

The commandnslookup queries the specified DNS server to resolve the fully qualified domain name (FQDN) of the NetWorker Virtual Edition (NVE) into its corresponding IP address. This is a forward DNS lookup, used to verify that the DNS server correctly resolves the NVE's hostname.

When Client Direct is enabled on a client resource, the NetWorker client pushes its deduplicated data stream straight to the AFTD (or DD Boost) device - bypassing the NetWorker storage node entirely - while still sending all control and metadata updates (client file index entries, media database operations, etc.) back to the NetWorker server so it can track and catalog the backup.
