# 路由中的docker转发问题

以docker运行nginx为例，开放80端口

docker run--name mynginx01-p80:80-it nginx/bin/bash iptables开放wan口80

数据包路径

ddns get: router lan address ↓ tcp port:80router wan ↓ ready forward to lan ---------- nat preforward: all port:80 and not from docker0 to docker0 ↓ ---------- filter forward: accept all to docker0 ↓ ---------- filter input: accept port:80 to lan from wan ↓ forward to router docker0 ↓ docker0:nginx

下面为iptables的配置

filter 表
