Thanks. You are right ntp proxy is absolutely what I want. Mine
description was not clean probably. So this is the setup:
GPSNTP(10.0.1.99/24) - eth1 myserver eth0 - clients(10.0.0.0/24)
Because GPSNTP is on a physically separated network I need this proxy
for my clients. My server is able to synchronize with GPSNTP so rules
are fine for that (because my output chain is ACCEPT per default). My
clients whom are cannot synchronize with my server even if I allow NTP
port which I do not understand.
Bye,
