NTP Multicast on a 3750

I have a subnet with a GPS clock on it that connects into a Cisco 3750. The 3750 has another subnet hanging off of it that connects into a firewall then to a server. I need the server to get time from the GPS clock. Can any one suggest a way to pass the NTP through the 3750?  The 3750 has the 3750-IPBase code running on it so the multicast support is limited. I am under regulatory restrictions that only allow traffic to flow from the higher security level (were the time server is) to lower security level (were the server is). This prevents me from having the server go to the clock for updates. Any help is appricated. Thanks.

If you are not allowed to open the firewall to allow NTP protocol through, then you can put the GPS on the same subnet as the server.
