  • you have to use port 443 for the lync web sites to forward to the Lync server.

    External 443 forward to 4443. If it possible to use the host header to select the correct forwarding.

  • Hi,

    Base on my understanding, you need to use TMG to achieve. Using TMG, create a listener with port 443, then create multiple rules for Exchange, Lync Reverse Proxy, Edge Server to use the listener you created above.
