AV communication and NAT network RRS feed

  • Question

  • I have read a others thread.

    But I not undestand if is possible to use a AV communication when i'm inside a NAtted network.

    I have installed e OCS and Edge Server inside my company. When i configure a public ip address on my laptop, the AV communication work fine. But when i had tested the AV communication from my house (ADSL over nat  - Simple router zixel), the connection was brocken before the AV communication.

    Thanks in advance.

  • On your pool, on the properties of your A/V Conferencing server, have you selected your edge server?

  • You can run the validation wizard on your OCS server and your Edge server. Try to fix any issues it finds, and then post any problems you may have here and maybe we can help.

  • Hi,

    This error means exactly as it says. You have configured Remote Access for users but the validation wizard could not find any edge servers.

    Can you let us know exactly what your setup is like? How many servers do you have? What are their roles? What you have enabled for your users? What works and what doesn't? (IM, video or voice internally, IM, voice or video externally, etc.)

  • Hi,

    Hi have a windows 2003 Active direcotry domain. I this domain i have installed OCS 2007 beta 3. I have one OCS Server and one Edge server.

    The edge server have a public IP address on the external network.

    I have enabled all for the users. Whe i use the communicator internally all work fine. But If i try to use the communicator when i am in other network a can use only the IM.

    I this second situation when i start A/V call or Audio call, the communicator close the calling.

    I hope that informations are useful
