[ntp:questions] linux ntp problem

I'm setting up a ntp server for a few servers we have that need to be
synced with the time but do not have access to the internet out of
their default gateway. So I'm trying to setup ntp on a localhost here
that has access to the internet but the internal servers can also
access that machine.

Here is my ntp.conf

server 199.165.76.11  # ntp.alaska.edu
server 204.152.184.72 # clock.isc.org
server 192.12.19.20 # montpelier.ilan.caltech.edu
server 207.200.81.113 # nist1.aol-ca.truetime.com


server   127.127.1.0     # local clock
fudge    127.127.1.0 stratum 13
#restrict default notrust nomodify

#restrict 127.0.0.1

logfile /var/log/ntp/ntp.log
driftfile /etc/ntp.drift


Here is the ntpq -p on the server 

[root at monitor ntp]# ntpq -p
     remote           refid      st t when poll reach   delay   offset
 jitter

And here is the result when trying to run ntpdate on the client

I don't understand why its not working.
