Hi ,

its work now , but i have to more problems ,

  1. if  i turn of the first ISP cable (dialer 1 ), the balance don't work  correctly , but if i turn off the second ISP cable ( dialer 2) , its  works
  2. normally i have 20 mb/s per ISP , and now , the  performance of browsing is very slow ,  , i think they are some ting  wrong with filtering
  3. the NAT for SMTP and Web servers dont work any more 

thinks for you support again
