LYNC server 2010

Posted on 2011-04-26

I’m in the final stage of opening our LYNC server 2010 implementation to external access but have a couple of questions regarding reverse proxy:
1)      The reverse proxy and edge server sit in the DMZ which is protected by a PIX firewall. Why do I need to run TMG 2010 on the reverse proxy server?

2)      Can I get away with Natting the necessary IPs/Ports to the DMZ interface?

3)      If the above are not possible, can someone point me to the necessary documentation on how to install TMG 2010 and get it operational for LYNC

    Accepted Solution

    1) TMG can function as a reverse proxy, you don't run TMG on a reverse proxy server. I don't believe other reverse proxy products are supported for Lync external access.
    2) I don't believe you can NAT the A/V edge interface, but I believe the other roles can be NAT'd
    3) This link should help with the procedure for using TMG to publish Lync URLs -

    Assisted Solution

    TMG (or the previous version ISA) IS a reverse proxy, so I don't understand your first question.

    And yes you can use NAT on all external interfaces with a single Edge server, but not with a load balanced pool of Edge servers.

    Where can I find documentation for install TMG2010 and configured specifically for LYNC.
