Windows下使用 netsh interface portproxy 进行端口转发

# 添加端口转发

netsh interface portproxy add v4tov4 listenaddress=<ip> listenport=<port> connectaddress=<ip> connectport=<port>

netsh interface portproxy add v4tov6 listenaddress=<ip> listenport=<port> connectaddress=<ip> connectport=<port>

netsh interface portproxy add v6tov4 listenaddress=<ip> listenport=<port> connectaddress=<ip> connectport=<port>

netsh interface portproxy add v6tov6 listenaddress=<ip> listenport=<port> connectaddress=<ip> connectport=<port>

例如将本地端口9999路由到124.128.64.179:8081端口：

netsh interface portproxy add v4tov4 listenaddress=127.0.0.1 listenport=9999 connectaddress=124.128.64.179 connectport=8081

参数说明：

listenaddress：本地侦听IP地址。

listenport：本地侦听TCP端口。

connectaddress：重定向到远程IP地址。

connectport：远程TCP端口，来自listenport的连接会被转发到该端口。

# 修改已经设置的端口转发

netsh interface portproxy set v4tov4 listenport=<port>

# 删除已经设置的端口转发

netsh interface portproxy delete v4tov4 listenport=<port>

# 清除所有当前的端口转发规则

netsh interface portproxy reset

# 查看已经设置的端口转发

netsh interface portproxy show all

# 查看端口是否已经监听

netstat -an | find "LISTEN"

注意：以上端口转发仅适用于TCP端口，对于UDP端口将不起作用。
