# /etc/ntp.conf: Configuration file for ntpd.
# External servers: The hostnames '*.pool.ntp.org' point to different
# servers each time, using a round robin system. If your ISP has an ntp
# server you want to replace these ones with it. It is not good
# practice to pick a 'stratum 1' server for the synchronisation of a
# single client, so don't put one here please. Read more about picking
# the right ntp servers to use at: http://www.pool.ntp.org/use.html

# Drift file. Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.

Your output shows that the ntp server could not be reached for 125 minutes. ntp uses udp for time transmission, you have to change your firewall rules.
