背景

服务器: centos 7
iptables 已关闭
阿里云端口已打开 80 端口, 关了 firewalld 即可外网访问可以证明这一点

现象

firewalld 打开即无法访问 nginx, 关闭即可访问 nginx, nginx 在服务器上通过 curl 可以正确显示, 在外网访问即无效
systemctl start firewalld, 外网无法访问, systemctl stop firewalld, 外网即可访问.

想不出来啥原因, 请大佬指点
备注: 此台服务器还有一个 java 程序, 关闭 firewalld 则无法访问该程序, 但把该 java 程序关闭掉, 现象也是和上面一样, 所以应该不是该 java 程序的原因

nginx 在 fireswalld 下无法访问, 希望大佬指点
