Serve NTP on the WAN

[rs232]

There are some peculiar cases where you might want to serve NTP information on the WAN, an example I can think about is an upstream modem/bridge with a locally significant IP only. This device will never be able to communicate towards Internet thus not a public NTP server. Allowing FT to respond to NTP queries on the WAN would solve this issue.

‌

I would suggest to modify the current NTP server settings from this:

‌

‌

into something like this:

Internal NTP server [Disabled/LAN only/WAN only/LAN & WAN]

Intercept LAN client NTP requests

‌

• For LAN & WAN it would mean adding to the iptables:

iptables -I INPUT -p udp -m udp --dport 123 -j ACCEPT

• For WAN only it means adding the above iptables + running the process as well (of course)

‌

Thanks.

So what is the difference between WAN only and LAN & WAN then?

[rs232]

The current enable is LAN only, in my example. LAN + WAN would also add the iptables command I suggested above.

[pedro]

Yes, :) I understand the difference between “LAN only” (now) and “LAN + WAN” (your suggestion, addition).

But what about WAN only?

[rs232]

Yes I think you have the point, perhaps “wan only” is not needed overall.

[pedro]

OK, now it’s clear ;)

GUI: Basic: Time: add option to serve also NTP on the WAN (resolves #234)
