DNS Filtering requirements and limitations

The N-central integrated version of DNS Filtering is no longer available for new activations. Only partners who have already enabled this feature will retain access.

For customers who want to use DNS Filtering’s features and functionality, we recommend using the standalone version. To view the standalone documentation visit the DNS Filtering User Guide.

For customers currently using integrated DNS Filtering, we need to connect with you to support your migration to the standalone version. Please contact an N-able representative and include your account name and contact information in the message.

Please note: The integrated version of DNS Filtering will be removed from N-central by 31 March 2026.

The following requirements and limitations are for typical usage patterns, acknowledging that some patterns may require more system resources for an N-able N-central server than others:

  • DNS Filtering is only available for customers who run N-able N-central version 2021.3 HF1 (2021.3.1.94) or later.

  • You cannot activate DNS Filtering on an NFR server.

  • Open port 8800 for outbound traffic to meet N-able N-central Networking Requirements.

  • You can activate DNS Filtering on only one server.

  • N-able N-central only supports DNS Filtering Roaming Client installation on Windows devices for now. Consider Site deployment for Mac and Linux devices.
