关于 OPNsense
OPNsense 是一个开源、易于使用且易于构建的基于 FreeBSD 的防火墙和路由平台。OPNsense 包括昂贵的商业防火墙中可用的大部分功能，在许多情况下甚至更多。它带来了丰富的商业产品功能集以及开放和可验证资源的优势。
OPNsense 于 2014 年作为 pfSense® 和 m0n0wall 的分支开始 (sysin)，于 2015 年 1 月首次正式发布。该项目发展非常迅速，同时仍保留了 m0n0wall 和 pfSense 的熟悉方面。对安全性和代码质量的高度关注推动了项目的发展。
OPNsense 每周提供少量安全更新，以在流行时间内对新出现的威胁做出反应。每年有 2 个主要版本的固定发布周期为企业提供了提前计划升级的机会。对于每个主要版本，都会制定一个路线图以指导开发并设定明确的目标。
功能 Features
OPNsense 的功能集包括高端功能，例如前向缓存代理、流量整形、入侵检测和简单的 OpenVPN 客户端设置。最新版本基于 FreeBSD 以获得长期支持，并使用新开发的基于 Phalcon 的 MVC 框架。
OPNsense 对安全性的关注带来了独特的功能，例如使用 LibreSSL 而不是 OpenSSL 的选项（可在 GUI 中选择）和基于 FreeBSD 的自定义版本。
强大可靠的更新机制使 OPNsense 能够及时提供重要的安全更新。
