# Enable Cloudflare Network Firewall

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/learning-paths/data-center-protection/enable-network-firewall/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Magic Transit customers are automatically provided with the [standard features](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-network-firewall/plans/#standard-features) of Cloudflare Network Firewall, Cloudflare's firewall-as-a-service product.

Cloudflare recommends creating a ruleset customized to your environment and needs. Without any rules configured, Cloudflare Network Firewall will pass on all traffic after mitigations are applied to your tunnels.

The [Extended ruleset](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-network-firewall/best-practices/extended-ruleset/) is the best practice for reducing your attack surface by adopting a positive security model. If possible, use your current Edge Firewall policies to help you decide what ports to permit/block.

If you cannot use the extended ruleset, then use the [minimal ruleset guidance](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-network-firewall/best-practices/minimal-ruleset/) to create a customized ruleset to block known unwanted traffic and common vectors for attack.
