Hi Rex,


Have you confirmed that port UTP/123 is allowed between the WAF Management path and the NTP server or the Internet (network firewall policy, router and switch ACLs, etc)?


There is an explanation of the Management path and Data path for Barracuda WAF here (https://campus.barra...954/networking/).


There is information about all the network ports and ranges used by Barracuda WAF here (https://campus.barra...e-installation/).


If you have confirmed this connectivity and you are still getting the NTP error, please contact Barracuda Support (https://campus.barracuda.com/support).
