这指导推荐使用 Gufw 防火墙 GUI。我通过安装它apt
gufw/oldstable,oldstable,now 12.10.0-1 all [installed]
graphical user interface for ufw
键入 ẁindow 键 + gufw，我看不到该应用程序。仅通过终端进行访问是gufw不够的。我在想为什么会这样+如何解决这个问题，因为我在 Linux 中系统地使用的防火墙太少了。
安装并测试已安装的软件包

Debian Stretch 于几周前发布。将整个系统升级到这似乎是解决您的难题的最简单的解决方案。
错误Debian Stretch 中的版本已修复，而旧的稳定版本 Jessie 仍停留在近五年前的版本上。
