>> add 200 allow udp from any 123 to any Is saying allow port 123 SOURCE packets in from any source, BUT client packets don’t come from port 123, but from an unprivileged port: here is a log from my internet facing server, also a 4801: Dec 28 18:23:58 muon kernel: ipfw: 540 Accept UDP 192.3.96.154:32894 192.168.1.4:123 in via sis0 so your rules are not allowing the outside requests to get to NTPns.
