[ntp:questions] NTP sync problem. "no server reachable"

Hi NTP experts,

I am facing a issue in getting the NTP to sync with the server configured.

Description:
I have a box which has 2 interfaces. One interface for the connectivity with 
the local-lan. The other
interface is connected directly to a linux box.

IP address details :
NTP server in the network -- 171.69.21.23
NTP server directly connected -- 10.1.1.1

When I configure 10.1.1.1 as my NTP server, within a few seconds I am able 
to see the sync.
When I configure the additional server 171.69.21.23, it goes out of sync. 
But I am able to see
the packet exchange happening.

Now if i remove 10.1.1.1 from the list, I get 171.69.21.23 into sync & 
vice-versa.

When I have configured both the servers, I see "no server reachable" message 
in the debugs.

Can someone please tell me what is going on here ?

My system is a regular Linux machine. I am running a older NTP version 
4.2.0a.

Regards,
Kiran S Shirol
