After redeploy `http-proxy` node, I can't access by going to `rc.uab.edu` on browser. Checking OpenStack deploy log, I found that the `firewalld` has been configured in `fail2ban` role: ``` [ 124.636919] cloud-init[1080]: TASK [fail2ban : Activate the firewalld support for fail2ban] ****************** [ 125.161650] cloud-init[1080]: changed: [127.0.0.1] [ 125.176262] cloud-init[1080]: TASK [fail2ban : Configure firewalld to allow ssh and sshpiper traffic] ******** [ 125.892330] cloud-init[1080]: changed: [127.0.0.1] => (item=2222/tcp) [ 126.441067] cloud-init[1080]: changed: [127.0.0.1] => (item=22/tcp) ```
