git clone ssh://git@gogs.magong.site:10022/mrh/Natter-v2.git

BIND_IP = 192.168.2.32 # 绑定的ip地址，需要将本机哪个网卡的地址暴露在公网上，尝试进行打洞
FORWARD_IP = 192.168.2.32 # 转发的ip地址，公网访问我时，将流量转发到局域网哪个地址上，用于查看访问是否成功
python natter.py -t $FORWARD_IP  -p 80 -i $BIND_IP -b 9820
# python natter.py -t 192.168.2.32  -p 80 -i 192.168.2.32 -b 9820

光猫设置

设置 DMZ ，可以将任意端口暴露在公网上，例如设置 192.168.2.31 ，说明该地址的防火墙是一个 Easy Nat ，轻松实现打洞

也可以设置端口转发，在某些光猫也叫 虚拟主机。例如我当前设置：
名称：随便；

# ❗❗协议一定要有两种
协议： UDP AND TCP 

广域网主机起始ip地址，广域网主机结束ip地址：不填；

广域网连接，选择路由模式的连接，也就是当前电脑使用的联网模式；

广域网起始端口，广域网结束端口，这个如果只有1个端口如80，就2个都填写80；

启用mac映射，这个不勾也是可以的；

虚拟主机ip地址，局域网内部IP地址，看你自己的网路连接的ip地址就可以了；

虚拟主机起始端口，虚拟主机结束端口，这个如果只有1个端口如80，就2个多填写80；

Natter (v2)

Expose your port behind full-cone NAT to the Internet.

In the example above, 203.0.113.10 is your public IP address outside the full-cone NAT. Natter opened TCP port 203.0.113.10:14500 for testing.

Visit http://203.0.113.10:14500 outside your LAN, you will see the web page:

It works!

Natter

Usage

usage: natter.py [--version] [--help] [-v] [-q] [-u] [-k <interval>]
                 [-s <address>] [-h <address>] [-e <path>] [-i <interface>]
                 [-b <port>] [-m <method>] [-t <address>] [-p <port>] [-r]

Expose your port behind full-cone NAT to the Internet.

options:
  --version, -V   show the version of Natter and exit
  --help          show this help message and exit
  -v              verbose mode, printing debug messages
  -q              exit when mapped address is changed
  -u              UDP mode
  -k <interval>   seconds between each keep-alive
  -s <address>    hostname or address to STUN server
  -h <address>    hostname or address to keep-alive server
  -e <path>       script path for notifying mapped address

bind options:
  -i <interface>  network interface name or IP to bind
  -b <port>       port number to bind

forward options:
  -m <method>     forward method, common values are 'iptables', 'nftables',
                  'socat', 'gost' and 'socket'
  -t <address>    IP address of forward target
  -p <port>       port number of forward target
  -r              keep retrying until the port of forward target is open

Read natter-docker for details.

Use cases

Expose local port 80 to the Internet, using built-in forward method:

python3 natter.py -p 80

Expose local port 80 to the Internet, using iptables kernel forward method (requires root permission):

sudo python3 natter.py -m iptables -p 80
