How can I change the NTP server in gateway?

Nebula production only support the fixed NTP server on domain 0.pool.ntp.org, 1.pool.ntp.org.

If your contury or ISP has not support these 2 domains, but only the specific domain then you can set DNS record for it.

For instance, if your local network only support domain of "abc.ph.ntp.org" and you can set it to DNS record.

Use "nslookup" to resolve the domain and find the set of IP address.

Use the domain that local net work has supports and put the IP of 0.pool.ntp.org to it.
