# ufw

[Uncomplicated Firewall](https://wiki.ubuntu.com/UncomplicatedFirewall)也称为`ufw`。是Ubuntu管理`netfilter`的命令行工具，用来简化默认的管理Linux内核防火墙`netfilter`的标准命令工具`iptabls`。

> Fedora/RHEL使用Firewalld]\(../firewalld/README)来实现相似的功能；据相关网上文章[Comparing and contrasting Uncomplicated Firewall and FirewallD](https://www.ctrl.blog/entry/ufw-vs-firewalld)对比，两者的差异主要是`ufw`功能更为完备，`firewalld`则趋向于使用zone来管理。
