I’m having trouble with the ntpd:

Firewall outgoing communication is blocked with just a few ports on a whitelist: ICMP, DNS, HTTP, HTTPS + NTP is allowed, but maybe this service also needs some additional ports?

The problem is that I find a filter log entry that shouldn’t be there:

because the RED / WAN interface is allowed to talk NTP to anywhere:

Since the reason of this problem is also related to outgoing firewall rules just like in this thread here:


i will search for a solution in the other thread.
