Linux firewalls —— 你的firewall是怎样建设呢？
[i=s] 本帖最後由 角色 於 2019-2-27 19:35 編輯 [/i]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。 [i=s] 本帖最後由 角色 於 2019-2-27 20:03 編輯 [/i]
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.
