  • Hi Lexi,

    Yes a reverse proxy server is required, the reverse proxy allows the web services of the Front End server to be published without exposing the Front end server directly to the internet. If also directs traffic inbound on port 443 to the Front end server on port 4443 so it hits the external web site of the Front end server. You also have a public certificate on the reverse proxy as well.

    A Microsoft qualified and supported reverse proxy list is 


    There are other solutions available but these are not qualified and would not be supported by Microsoft if theres was any issues. You can uses a windows server with IIS ARR for example.

    Hope this helps.

  • do you have external users in this case or Lync mobile users ? if no it is not really needed

    if yes a reverse proxy is required  actually reverse proxy is needed for below scenarios:

    *download meeting content, expanding distribution groups, downloading files from Address Book Service, and PowerPoint presentations rendered by Office Web Apps servers) requires users to be able to access these services using the external FQDN configured for these services

    *also mobile device will use SIP encapsulated within HTTPS for signalling and https traffic will flow through the reverse proxy
