Create a Network Exception

To limit the visibility of an NFS share, it is strongly advised to create appropriate network exceptions that apply to projects or individual shares to limit the clients that are able to mount or access the share. Network exceptions are defined based on IP addresses, Fully Qualified hostnames, or Subnets, and indicate that, for a specific share or project, only those clients fitting the exceptions definition can see or use the NFS share.

  1. Select a project or a file system, based on how you want the exception applied:

    Navigate to one of these options:

    • Project – Allows all shares within the project to inherit the same exception configuration.

    • Share – Configures a specific exception for just that share.

  2. Double click the Share or Project from the list in the window to start configuring the exception.
  3. Navigate to the Protocols tab to start configuring an exception.
  4. If applying an exception to one share and not all of a projects shares, you must uncheck the Inherit from Project box at the top of a shares Protocol page to enable editing of a specific exception for a share.
  5. In the NFS field of the Protocols screen, set the Share Mode to None.

    This prevents the NFS share from being mounted by any client and allows only access to clients that match the exceptions that are being created.

  6. Click on the + symbol next to NFS Exceptions to create a new exception.

    Select a TYPE from the drop down menu option:

    1. Host(FQDN) or Netgroup – Enter an Entity IP address or fully Qualified Domain Name hostname.
    2. DNS Domain – Enter a DNS Domain that will be able to access the share.
    3. Network – Specify a network subnet in CIDR format (aaa.bbb.ccc.ddd/nn) that will be able to access the share
  7. Complete the Exception information by choosing a suitable Share Mode, Charset, and whether Root Access is required.
  8. Multiple exceptions can be added if required.
  9. Click Apply to check and apply the exception.
