When I (and another person) query using a simple sntp client then it seems 
to work okay. All that my client is is the msntp [1] program slightly 
(about 4 lines) modified to always return the same time and to listen on a 
different port. The iptables rule is just:

iptables -t nat -A PREROUTING -p udp --dport 123 -d -i eth0 -j 
REDIRECT --to-port 11123

The server definately notices the queries coming in and complains they are 
the wrong length (can't check the exact error message from here). So I am 
suspecting a bug with msntp.

I've not had people try anything other than standard ntpd[ate] and the 
python script against it though.
