今天，Linode很自豪地介绍我们的云防火墙测试版；这一免费产品使客户能够在他们的云基础设施上设置一个额外的安全层。
云防火墙通过在Linode网络层面过滤流量，增强了你对谁可以接触到你的网络应用或数据的控制水平。云防火墙很容易在云管理器中进行设置。你可以在你的每个Linode上一次应用多达三个云防火墙。
云防火墙作为一个带有隐含拒绝规则的允许列表工作。启用后，它默认会阻止所有入站流量。只有符合配置的规则参数的网络流量才能通过。如果没有设置出站规则，所有出站流量都被允许。
云防火墙是进一步简化Linode的云基础设施管理的下一步。这项免费服务的设计是基于一系列使用案例的极度可扩展性，并使所有Linode客户更容易获得安全的最佳实践。
加入测试版
Linode正在寻找用户对云防火墙进行测试并提供反馈。该测试版目前在我们的悉尼、孟买、亚特兰大和多伦多 数据中心活跃。欢迎任何Linode用户参与，但你需要在这些数据中心之一创建资源。
云防火墙测试版适用于任何在测试版支持的数据中心拥有资源的客户。通过阅读我们关于添加和配置Linode云防火墙的指南来开始。云防火墙在测试版和推出后都是免费产品。
云防火墙将在未来几个月内根据你们的反馈意见，进入全面供应阶段，并向我们的其余数据中心推出。请关注我们的博客，注册我们的每月通讯，或在Twitter上关注我们，以获得最新的更新。
防火墙测试版可用性最后更新于2021年4月13日。

Looks great! How will this work together with the managed Kubernetes? Will it allow to add all (future) servers from the cluster?
Hey Laurens – as this new product is still in beta testing, we don’t have a specific answer for how it will work with LKE. We’d love for you to try it out and share any feedback you have.
Once we complete testing, we intend to roll this out to all data centers, though there isn’t an ETA on when or which data centers would be first.
And here I was just about to contact support to find out how to set up firewall rules… Great job, humans! 🙂
great, what is the time frame for the NJ data centers?
Hey Jeryl! We don’t have a release date for our other data centers just yet. But we’ll be sure to mention it on our blog when we have more information.
I was just about to contact Linode Support to see if they might plan on implementing an account level web-based firewall! We must be on some psychic wavelength, because here we are–it was just released!
Finally the most needed feature is here, just waiting for official launch.
It is worth noting: whether it can be officially released before 2021
While we don’t have a specific date for this to enter into general availability, we encourage you to try it out in beta. We’d love your feedback.
