Lync Web Certificate RRS feed

  • Question

  • Hi Experts,

    When external users join Lync conference by Lync web app, they will get a error "Content was blocked because it was not signed by valid security certificate" as below capture. I donot configure the Lync reverse proxy, only have the NAT on firewall, whether I may apply for a public certificate for my front end server.

  • The recommended way to do this is to have a reverse proxy with your public cert on it.  Then when external users connect they will be presented with a cert they can trust.

    There is, however, no technical reason why you can't put a public cert on your Front End.

    Keep in mind, however, that your external users should be hitting the external web site on ports 4443 and 8080.  Without a reverse proxy you must do port translation on your firewall to ensure your external web connections to 443 will land on 4443 on the front end.
