Creating DNS Records

The CTERA Portal includes a built-in DNS server. This server automatically resolves the domain names of all the defined virtual portals, as well as names of devices using the remote access service. In order for this DNS server to work, you must register it using an NS (Name Server) record on your DNS server.

The procedure used for configuring the DNS for remote access depends on the whether you have purchased a dedicated domain (the DNS suffix includes only records for the CTERA Portal) or not (the DNS suffix includes records that are unrelated to the CTERA Portal).

If you have a dedicated domain:

• If you have a dedicated domain for the CTERA Portal – no servers other than the CTERA Portal – then the NS record can be created just once, in that zone.
  For example, for a DNS suffix called storage.example.com and two CTERA Portal servers with IPs 123.168.0.3 (primary) and 123.168.0.4 (secondary), you would register:

  A             srv1.example.com                 123.168.0.3
  A             srv2.example.com                 123.168.0.4
  

  Next, you would create an NS record for each server to the zone storage.example.com:

  NS          storage.example.com          srv1.example.com
  NS          storage.example.com          srv2.example.com
