Hi,

I find the solution , the proble come from conntrackd.conf it was made 
from the one on a squeeze and with the example bring with the package a 
made this one :

Sync {
     Mode FTFW {
         DisableExternalCache On
     }
     UDP {
         IPv4_address 10.98.145.5
         IPv4_Destination_Address 10.98.145.6
         Port 3780
         Interface eth2
         SndSocketBuffer 1249280
         RcvSocketBuffer 1249280
         Checksum on
     }
}
General {
     HashSize 8192
     HashLimit 65535
     Syslog on
     LockFile /var/lock/conntrackd.lock
     UNIX {
         Path /var/run/conntrackd.sock
         Backlog 20
     }
     SocketBufferSize 262142
     SocketBufferSizeMaxGrown 655355
     Filter {
         Protocol Accept {
             TCP
         }
         Address Ignore {
             IPv4_address 10.98.0.0/16     #dedicated link #
         }
     }
}


diff :
                 old         new
HashSize  32768   8192
HashLimit 131072 65535

- NetlinkBufferSize 2097152
- NetlinkBufferSizeMaxGrowth 8388608
- NetlinkOverrunResync On
- NetlinkEventsReliable Off
- PollSecs 15
- EventIterationLimit 100
- Filter From Userspace {

+ SocketBufferSize 262142
+ SocketBufferSizeMaxGrown 655355
+ Filter {

can someone look at my new conntrackd.conf and says if i forget 
somethinks important ?.
