Server time update problem

i have few servers with sles 11sp2 which have problems updating time from local server.
After some investigation i found out that server is comuticating via high ports which are blocked cause servers are in dmz. Is there a way to force using 123 port.

I’m trying to updiate via
#ntpdate LANtimeserver
#sntp -P no -r LANtimeserver
sntp: not enough valid responses received in time

i can see the time via, but still can’t force to update system time.
server3:~ # ntpq -p
remote refid st t when poll reach delay offset jitter

*LANtimeserver othertimeserver 4 u 62 64 377 0.907 -339.52 117.901
LOCAL(0) .LOCL. 10 l 31 64 377 0.000 0.000 0.001

any advise how can i force to update from time server. Only port available 123.
Thanks in advance.
