I need help if you experience this issue and what was the root cause. My Sidewinder firewall is pointing to Public NTP server fully qualified domain.
Last 2 months it was working but suddenly wan link become saturated. I just notice from wireshark when I run I able to see that fw is getting a lot of outgoing traffic to public NTP server.
I backup the files before removing the Public NTP server and notice fw backup file when i download it reach upto 54MB which is normally 18MB.
Any I dead what could be the issue here? Thanks
I will not point again my fw to Public NTP server which i know the risk is high.
