Bluewall 是一个为进攻型和防御型网络专业人士设计的防火墙框架。 该框架允许网络安全专业人员快速搭建其环境，同时保持在授权范围内。
灵感来源于 Andrew Benson 的 hostfw iptable 生成脚本。
* 配置防火墙
* 配置主机名
* 配置网络接口
* Redhat/CentOS
* 可生成 Windows 配置，但不执行。
* bluewall -c config/example.ini
** 参阅示例配置
* 枚举 - 识别网络中的在线主机（即将推出）
* 目标主机 - 出站通信
* 信任主机 - 双向通信
* 禁止通信 - 计算机不应与之通信的设备

A python framework to automate firewall setup.
Defaults:
Outbound connections will be allowed on all ports to all hosts.
Inbound connections will be limited to related outbound traffic.
DHCP will be enabled.
Ping responses will be enabled.
Unsolicited inbound connections will be dropped.
optional arguments:
-h, --help show this help message and exit
-V, --version Display Version
-v, --verbose Verbose Mode
-r, --reset Send TCP RST instead of dropping packet.
-p, --disallow_ping Disallow incoming PING
-i, --allow_outbound_icmp
Don't restrict ICMP types
-d, --disallow_dhcp Disallow DHCP
-w WINDOWS_CONFIG, --windows_config WINDOWS_CONFIG
Generate Windows Configuration. Usage: bluewall -w
