Nokia NTP source-interface

[bugueur]

Hi all,

I am facing a strange problem with my IP-290 cluster (VRRP)
Every thing works perfectly except the NTP that doesn't work for the passive member.

In fact, both nokia devices are configured as NTP clients and the server is located in a directly connected network.

A tcpdump shows that both nokia appliance uses their VRRP address as a source interface to query the server. When the backup device uses this address, it never see the reply and obviously, this generate a deny statement in my log file since the active firewall receive an unknown reply :-(

My question is quit simple, do you know guys how to specify the source interface on Nokia devices ?

Many thanks in advance for your help
