Hi, I cannot reproduce your problem. It looks like your connection is dropping
data for ntp. Why are you using ntp from ports instead of base? do you or your
ISP block any ports outbound?

output from a machine on my network that's behind NAT. system is stable/13 and
ntpdate is 4.2.8p15-a as is ntpd

in my /etc/rc.conf there's this:

ntpdate_enable="YES"
ntpdate_hosts="uk.pool.ntp.org"
ntpd_enable="YES"

output:

% ntpdate -d 0.freebsd.pool.ntp.org
