Hello everyone,
I just connected a freshly installed OPNsense via PPPoE to the internet and watched the Firewall Live View a bit. What caught my attention are hundrets of connections to various different IPs, going from and to Port 123. Sometimes the entire page was only "123" connections and a few block inbound ones:
https://ibb.co/9YJV2yC (https://ibb.co/9YJV2yC)
And indeed, on the Status page of the Network Time Service, I found a lot of these IPs again:
https://ibb.co/x6rS5mc (https://ibb.co/x6rS5mc)
The configuration of the Network Time Service is completely untouched. Only those [0-3].opnsense.pool.ntp.org servers are configured with the first one being prefered.
Is there something wrong with the default settings:
https://ibb.co/HpQfP2Q (https://ibb.co/HpQfP2Q)
How can I make the Network Time Service only try one server and not connect to so many?
Thank you.
If you really want that, just use servers, not pools.
Your 3rd picture does not show the top of the page where it gives the number of servers you are looking at.
