Configure file storage access for specific IP addresses or subnets

You can configure file storage access for:

  • all IP addresses of the private subnet where the storage is located;
  • specific IP addresses;
  • other private subnets.

To configure access to the file storage, you need to add rules or delete rules. For each rule, you can select a specific access level. Rules can be added:

Access levels

Depending on the file storage protocol, you can assign an access level to the storage:

  • for CIFS SMBv3 — read and write (rw);
  • for NFSv4 — read-only (ro), read and write (rw).

Add rule

For your information

A new access rule list for file storages with the NFSv4 protocol is applied within 15 minutes after adding or deleting rules.

Rules are applied in the order they appear in the list — from top to bottom:

  • a rule for accessing the storage from any IP address of a private subnet (0.0.0.0/0);
  • access rules from private subnets (for example, 192.168.0.0/29);
  • access rules from specific IP addresses (for example, 192.168.0.10).
note

For example, if the rules 0.0.0.0/0, 192.168.0.0/29, 192.168.0.1 are added, access to the storage will be open from any IP address of the private subnet.
