为了建立好的firewalls基础知识，所以我从新整理过这幅帖子。在还没有讨论firewalls的建立，我们先收集一下关于一些Linux firewalls的资料，方便参考和讨论。

From [1], I got two references [2,3]。 Reference [2] is the primary source for building up firewalls using iptables commands.

Ref. [4] provides a very brief introduction of firewall using iptables commands.

Ref. [5] also shows that iptables commands are the most popular firewall commands used in Linux systems. There is a packet flow diagram showing the details of packet flows.

If you can find the book name Linux Firwalls [B1], which will give you an overviews of what Linux Firewalls are.

哈哈七年了都没有写过东西的帖子，这次为了学好建立firewalls，我都是从Linux开始，因为很多device的GUI都源自于Linux，例如MikroTik routers。

我看很多Router的firewall and nat都是源自于Linux firewall and nat，所以认真理解Linux 的firewall and nat对其他router有非常大的帮助。
