File Transfer Issue - Communicator 2007 RRS feed

  • Question

  • Environment:

    We have one OCS 2007 FE server and one OCS 2007 Consolidated Edge server.

    Issue:

    I have few users who can send files through Communicator 2007 but cannot receive files.

    I have also users who don’t have any issue in sending/receiving files.

    I have few users who even cannot send/receive files.

     

    Questions:

    Are there any known reasons why it works for some users and not for others?

    Do I have to allow TCP ports 6891 – 6900 on our firewall for external file transfer?

     

    With best regards,

    MFSAEED

  • File transfer is peer-to-peer TCP 6891-6900 from to/from everywhere for file transfer to work (not sure about double nat issues)
