I'm havinf NTP configuration problems

Hi,

I'm not sure if anyone can help me with this issue. I'm trying to configure NTP on my router to sync it's clock with a public time server. It's not working, but it's talking to the server..

Here is the debug, the host 192.168.10.1 is the reply from my firewall.

----

12w3d: NTP: xmit packet to 131.188.3.220:

David,

I've had routers that didn't change to reflect the data they receive trom an NTP source, and the problem was traced to the fact that the routers' configurations had the command "ntp master". See if your config has this command, and if so get rid of it.

Re: I'm havinf NTP configuration problems

Dave,

I just noticed the bit about the address of your firewall in the NTP RCV packets in your debug trace. Your router is expecting to receive NTP packets from 131.188.3.220. Is your firewall is translating this address to its own IP address on VLAN 10?
