  Hi,
  
  if you are not using ocs forefront, then file transfer traffic is peer to peer communicator traffic through ports 6891-6901.
  
  So if you are using pat for your internal clients than it seems to be a firewall issue.
  
  Hope that helps
  
  Bye

  Hi,
  
  thanks for the reply!!
  
  Do you mean I need to check the local firewall clients? I also opened range tcp 6891-6901 from intern to extern on the firewall, but no go...
  
  Thanks!

  traffic has to be allowed bidirectionally for both sides.

  And other, the issue maybe carsed by the network router problem, please ensure that, you use the netmon to check the interactive connection between the internal and the external.
