Description of problem:
  
  When we have an IPv6 Ready Logo Phase-1 Self_Test,we found many tests to 

fail.From the shown logs,it seems that TN doesnt observe the corresponding 

packets from NUT when test scripts running on TN send some packets to NUT.

Version-Release number of selected component (if applicable):

  kernel-2.6.18-43.el5

Software Environment:   
  
  Testee(NUT):   
    RHEL5 
    Kernel:2.6.18-43.el5 
   
  Tester(TN):   
    FreeBSD6.2 
   
How reproducible:

  every time

Steps to Reproduce:

  1. Configure TAHI test environment.     
  2. Run the TAHI test suite     
  3. After the test completes, check for the results
  
Actual results:

  TN can not observe corresponding packets from NUT.

Expected results:
