ntpd communicates directly with your remote time servers via port
123/UDP. You need to have direct access to your remote time server(s)
via the NTP port.

That's an HTTP proxy. There is no such thing as an NTP proxy.

If the proxy server is also a time server (i.e. is running ntpd) you can
specify the proxy server on a server line in /etc/ntp.conf
If the proxy server is not running ntpd and you can't have direct access
to port 123/UDP form the private network your only solution may be
htpdate (which does work through a proxy):
htpdate(8) man page http://linux.die.net/man/8/htpdate
