The ntp.conf on the clients.

ntpd binds all of the interfaces. So you can point your clients at the
IP address of the interface they are connected to. Then you won't have
to complicate your configuration with unnecessary routing.

Is your server synced to a source of time (e.g. remote time server or
local ref-clock)?

Is port 123/UDP open on both your server and its clients?

Are there any restrictions which may be blocking ntp packets between
your server and its clients?

Have you tried pointing your clients at the server's internal interface?
