Your server has stratum 15 because it is not synchronized!! No idea why
your client is claiming stratum 1; it should not be unless it is being
synchronized by a hardware reference clock.
NTP was not designed to synchronize clocks to each other. It was
designed to synchronize clocks to UTC. That clients have the same time
is a happy consequence of the postulate "things equal to the same thing
are equal to each other"!
The most recent version of ntpd supports an "orphan mode" for use in
isolated networks. It don't know how to configure it; see the
documentation (links at http://www.ntp.org/)
If you insist on abusing the tool, the ready made "solution" is to
configure your "server" as a client of the the "client" that is claiming
stratum 1. Of course this will break if the "client" ever stops
claiming a stratum it is not entitled to. And PLEASE do not connect
this mess to the internet!!! (Somebody might believe that bogus stratum 1!)
