More info: I now have the triple homed server communicating and syncing with the firewall. Also, the triple homed server is broadcasting onto subnet B and C (I can see this with tcpdump). However, each of the clients on subnet B and C never process the packets. Here is a sample "sysstat" from ntpdc on one of the subnet B boxes: system uptime: 14105 time since reset: 14105 bad stratum in packet: 0 old version packets: 28 new version packets: 219 unknown version number: 0 bad packet length: 0 packets processed: 0 bad authentication: 0 limitation rejects: 0 Why zero packets processed? Running ntpdate -d from subnet B or C shows: transmit(10.0.0.1) transmit(10.0.0.1) transmit(10.0.0.1) transmit(10.0.0.1) transmit(10.0.0.1) ... For some reason, the B and C clients aren't communicating correctly with the triple homed server. Yet, his netstat shows udp port 123 open on each interface. People on subnet A have no trouble communicating with the firewall's ntpd. Ideas anyone?
