A lot of unknow-udp traffic (port 123)


I observed since 04/09 a lot of traffic clasified as unknown-udp from my DMZ to Untrust. It could be missidentified because I have security rule that allow NTP.

It could be related to 429 package of Thread prevention update. Now I'm on 430-2169.

Do You have the same?

I had some unusual behavior with DHCP using application-default for the service.   However it identified DHCP using Service Any.   You might try something like that as a test if that sounds familiar.

NTP content was modified in content 428 to counter certain apps that were using the same udp port 123 to pass traffic. The behavior has been corrected will appear as such the next release.
