Dear members, Please tell me what's wrong. After setig firewalld, I got fail on cloud-init with reboot. The server is rebooted, but I cannot access from internet. Before reboot I can access form internet. And before setig firewalld, there's no problem on reboot. /var/log/cloud-init.log shows following Jul 17 14:18:46 biz105 cloud-init: ci-info: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Route info failed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
