Firewall and NTP

Unanswered Question

I am experiencing a strange problem with my Pix525. A device outside the firewall attempts to communicate with a NTP server on the inside of the firewall. I have a line in my access list allowing communication from the outside host to the inside host on UDP 123. I successfully sniff packets on the outside of the firewall from the outside host to the inside NTP server. The counter for the access list entry increments as traffic from the outside host attempts to communicate with the inside NTP server. Unfortunately the packets are being dropped by the firewall after being processed against the access list. This is verified with a packet sniffer. NTP sync fails. I am running PIX code 7.0(2)5. Thanks in advance.
